Summary:
Sometimes, valid Eo objects of private classes can be returned from
methods. Currently we try to wrap in a minimal `Efl.Object` instance,
but as it is an abstract class, we can't instantiate directly.
This commits adds a dummy `Efl.ObjectRealized` to be instantiated when
wrapping such classes alongside a test case.

Summary:
Eolian allows non-public members in interfaces and mixins (usually
@protected). As both kinds are converted to C# interfaces, this
causes problem as non-public members are forbidden in C# interfaces.
This commit changes eolian_mono by removing those members from the C#
interfaces. If a generated class implements the interface, the method is
generated as if it were a protected member of the class directly.
For mixed properties like `Efl.Io.Reader.CanRead { get; set @protected; }`,
the interface has only the public getter and the the implementing class has both
the public getter and the protected setter.
With this, C# devs won't be able to directly implement protected Eo
methods from interfaces. (But this really does not make sense from the
C# point of view).

Summary:
This commit makes use of the `ownership,shared` and `ownership,unique`
events from Efl.Object in order to avoid the C# wrapper from being
collected while C code holds a reference to the object.
For example, creating a list of items in a for loop and attaching events to
them would fails without this commit, as the C# GC may collect the wrapper.
The basic idea is that we use a `WrapperSupervisor`, which is stored in
the Eo data storage, with a GCHandle allocated for the lifetime of the
underlying Eo object. This supervisor takes care of holding either a
weak C# reference (when in unique mode, allowing the wrapper to be GC'd)
or a hard C# reference (when in shared mode, making the wrapper
non-collectable while the Eo has extra references).
One limitation is that object graphs can leak if a shared object in the
graph - an Eo child for example - stores a hard reference to another
object in the graph as a C# field. In this example, this causes the
parent to always have a hard C# reference (from the child) as the child
is non-collectable due to the parent holding an Eo reference to it.

Summary:
Rework general event handling to check individually each event call, if the
object is not alive then the event will not be propagated.
WeakReferences (and lambdas capturing those WeakRefs) are used to ensure this.
Dispose methods in object now take care of checking if efl libraries are still
initialized and thread-safely unregister each event before performing an
efl_unref on the Eo object.
Event handling in C# is now centered around a single dictionary inside the
object: `EoEvents`.
C# event triggers now properly trigger events on C too.
Standardize C# event-triggering methods names (remove underscores).
Some diminished use of static memory due events no longer requiring static key
objects to be registered/unregistered.
Some fixing of white space generation for generated events.

Summary:
Abstract Eo classes are now proper C# abstract classes.
As a side effect, returning Eo instances from native code was reworked
to return instances of their actual Eo classes instead of previous
behavior of returning a generic Efl.Object and using static_cast.
Instead of `var window = Efl.Ui.Win.static_cast(widget.GetParent());`
Use `var window = widget.GetParent() as Efl.Ui.Win;`
Another side effect was that `efl_constructor` was removed from the list
of supported `Efl.Object` overrides. It is invoked inside
`efl_add_internal_start`, before the bindings makes the association of
the newly created EoId with the C# instance that created it, making the
managed delegate meaningless. C# users then can use regular C#
constructors to initialize fields.
Also changed to set the private data of C#-inherited classes before the
call to constructing methods (aka constructor parameters) so C# classes
can override them correctly.

Summary:
In order to work around an issue with Efl.App, which is stable but
inherits from Efl.Core.Command_Line, @beta interfaces/mixins in the
inheritance chain are simply skipped.
Also changed the class used int test for inheritance from C#
Efl.Loop is stable but internally it uses a @beta class as argument to
its Register() method in the constructor. When instantiating a
user-defined C# subclass, the binding calls the C# override in the
NativeInherit class and the marshalling fails as no code is generated
for the beta class.
Also moved Efl.Part test to a beta class. Efl.Part is still beta.
Regarding parts, they are skipped if its class is @beta too.
Also rejected all elm_* files in elm public eo files. They should get
back in as they are converted to Efl.Ui.* api. An exception is
elm_interface_scrollable.eo, as efl_ui_panel depends on it.

Summary:
This commits adds dotnet as a supported C# platform for EFL# bindings.
Due to differences between Mono and Dotnet regarding DllImport, the
bindings now are using an imperative approach to load the function
pointers through the NativeModule and FunctionWrapper classes. These
classes handle the dlopen/LoadLibrary and dlsym/GetProcAddress calls.
Also, the previous caching of non-owned strings returned to native code
was removed until further memory checks.
We also had to create workaround for bool and chars in Structs for C#
marshaling. Going through System.Byte instead and Marshaling manually
to their respective types.
In order to actually build efl_mono.dll with dotnet right now,
issue #4782 from Meson should be fixed to make it properly detect and
used the Dotnet compiler. Also use "-Ddotnet=true" when running meson.

This commits adds support by representing Efl.Class instances

Summary:
After the new API, the virtual wrapper classes (*NativeInherit) just
declared the wrappers for the current class. But as they didn't have any
inheritance information, reimplementing methods from a parent Eo class
wouldn't work. (e.g. Efl.Ui.Button reimplementing Efl.Object
FinalizeAdd).
This commit changes these NativeInherit classes to mimic the inheritance
chain of their regular/abstract counterparts, reusing the virtual
wrapper implementations.
In order to access the correct Eo class created, the methods on it were
changed from static to instance methods. The instance will be held as a
class member of the regular/abstract API class to keep the delegates
alive and allow getting C Function pointers from them.
The class_initializer method was also split in two. The method
collecting the wrapper delegates was extracted in order to call the
parent ones.
Also avoid exception in cached strings queries as TryGetValue requires
non-null keys.
Test Plan: Run test suite.

Summary:
As discussed in T7204:
- Eo Interfaces/mixins -> C# Interfaces with concrete class
implementations
- Eo Regular/Abstracts -> Proper C# classes
- Added some new generators and helper methods.
- Refactored the class generator, splitting into helper methods
Eo handles now are stored only in the "root" class in any given
inheritance tree (generally, Efl.Object), and accessible to each child.
Methods also are defined in a single place instead of repeatedly
generated in everyfile, reducing the size of the generated .dll from
30MB to around 4.5MB.
Mixins are generated as C# interfaces but any regular class it inherits
from is lost, as we can't have interfaces inheriting from regular
classes. This will be dealt with in a later commit.
Summary of API Changes:
- Merged Inherit/Concrete classes. (These suffixes disappear from
regular classes).
- Interface still have implementations with 'Concrete' suffix for when
they are returned from methods.
- Removed 'I' from interface names.
- Removed interfaces for regular/abstract Eo classes.
- Concrete classes for interfaces/mixins hold the event argument struct.
- Removed '_' from classes, enums, structs, etc, as indicated in C#
naming conventions.
- Namespaces are now Camel.Cased.
- Renamed IWrapper's raw_handle/raw_klass to NativeHandle/NativeClass
Also renamed the test classes as after the namespace change, the
test namespace Test can conflict with the helper Test namespace.
(And use more meaningful names than Test.Testing...)
Also Fixes T7336 by removing a deprecated example and adding
efl_loop_timer_example to build system.
Fixes T7451 by hiding the class_get DllImports and renaming the IWrapper
fields. The native handlers are used in the manual binding.
Still need to work:
- As there are still some events names clashing (e.g. Efl.Ui.Bg with "resize"
from Efl.Gfx.Entity and Efl.Gfx.Image), Events are currently declared on
the interface and implemented "namespaced" in the classes,
requiring the cast to the interface to access the event.
- The Mixin Conundrum. Mixin inheritance will be dealt in a future
commit.

Due to the absence of typedef from C#, we generate thin structs with
implicit operators to allow reference the data from their typedef'd name
from C#.
The other alternatives would be always converting to the lowest base on
the alias stack (losing the meaningfulness of the typedef name) or using
the 'using' directive. The latter has the restriction that it makes an
alias visible only in the file they are declared.
