Summary:
These constructors aren't checked for in the finalize step of the
initialization and may be given the @optional tag.
For C# this means they can be ommitted from the constructor call.
This also adds `Efl.Ui.View.model` as a constructor of
`Efl.Composite_Model` as the finalizer checks for it.

Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).
