This fixes the usage of the Efl.Loop.arguments event.
Also renamed the ToExternal methods to ToManaged, to make clearer that
the output struct is the one intended to be used from the managed code.
Also fixed a minor styling in the generated code (making it easier to be

Summary:
new Eina.Value(0) is a special case. The 0 is silently converted
to an enum (Eina.ValueType) and therefore the call is ambiguous
with the 0 being first converted to an Eina.Value via the implicit
conversion operator (calling the Eina.Value deep copy constructor).
Adding constructors for all supported types solves the problem because
they have higher priority. Also, they avoid one deep copy of the
Eina.Value.
Includes test case to catch this problem in the future. This was discovered
in the tutorials, where new Eina.Value(0) is being used.
Test Plan:
The src/efl_reference_core_event.exe example from the examples repo was
not compiling before, and now it is.

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.

The interface efl_part_get should not be directly called from C, but the efl_part

Previously, class methods were implemented as regular instance methods.
This commits generates C# static methods for @class methods on the
*Concrete classes (and their childs).
Function pointers now go through the same argument marshalling pipeline
as normal functions.
This will enable interfaces like Efl.Ui.Format to work properly.
When we have an eina.Value_Native (representing an Eina_Value passed by
value) and assign it to an eina.Value (a class with an IntPtr to an
underlying Eina_Value) we copy it so the eina.Value can take ownership
and free the data normally.
A possibly better alternative would be adding an extra flag to
eina.Value (something like OwnsPointer) to check whether we should free
the struct we point to or not.
Instead of
var bg = efl.ui.Background.static_cast(myobj.Part("background"));
Now do
var bg = myobj.Background;
Also a couple helper functions were added.
In general, ptr(struct) parameters behavior depends whether the
parameter has the @owned modifier or not.
If there is no @owned parameter (meaning no transfer of ownership
happens) and it is a "complex" struct, with reference type fields
(like strings), the struct is converted to the respective
<Struct>Internal struct and passed with "ref" to the DllImport'd
function. For @in parameters, after the function it returns, this
intermediate struct is converted to the public struct type and
assigned to the original parameter, updating it to the external
world.
When we have ownership transfers, the structure is copied to unmanaged
memory and given to the callee. We can't send managed memory directly as
the callee may try to free it. On the managed side, the original struct
is left to be garbage collected normally.
Summary:
C# does not have a literal form for structs (like C++'s {} aggregate
initialization). Before this commit the user would need to explicitly
instantiate a struct and assign the required values to it, like:
eina.Size2D size;
size.W = width;
size.H = height;
widget.SetSize(size);
As a workaround, this commit generates helper constructor with
parameters corresponding to the struct fields in the order they are
declared. These parameters have default values if one does not want to
explicitly initialize all fields directly. With these constructs, the
above code could be translated to:
widget.SetSize(new eina.Size2D(width, height));
It should be noted that the constructed struct will live on the managed
memory (GC) instead of the stack.

This commit adds the "documentation" generator, which gets the
documentation_def attribute of the given item and generates xml comments
to be exported by MCS.
For items requiring some customization of the generated comments (e.g.
functions and its parameters), the helpers to generate the preamble
(summary), body (paragraphs) and epilogue (currently just the @since
tag) were added.
Currently we do not support converting Eolian references into xmldoc
references.
As we explicitly generate Get/Set methods for properties, for now the
generator tries to get the get/set specific documentation first. If it
is not present, fallback to the common docs.
Later this could be changed to generate the common one as paragraphs of
the Get/Set.
Also some generated code like the wrappers for calling C# methods
from C can be private. This will cleanup the introspection results
and warnings when generating documentation.
Due to this visibility change, the binbuf tests had to be changed
to add redirect calls to the native methods instead of directly
calling the DllImport'd methods.
