Allows polymorphic conversion of of Gd<T> to DynGd<T, D> (without direct AsDyn relation, only through derived classes). Co-authored-by: Yarvin <[email protected]>
Also unit-test each of them.

Follow-up to #953.
Many thanks to @Yarwin, who supported me throughout the design + implementation phase (also with great ideas from #930), and helped a lot with testing! 💪
This enhances the bare-bones #953 with a ton of traits to integrate with Godot, most notably:
DebugDisplayEq+PartialEq+Hash(reference semantics likeGd)ToGodot,GodotConvert(pass as object to Godot)FromGodot(hard*)ArrayElementAsArg+ParamType.The
DynGdAPI is extended to includecast+try_cast, as well as a lot more documentation.Also improves some error messages for existing conversions.

FromGodotwas particularly difficult, because we need to obtain adyn Traitpointer from the aether (Godot doesn't have it), and make sure it points to the correctimpl Traitvtable. Thanks again for the digging, Yarwin!
