C#: Re-introduce generic Godot Array and Dictionary

This new version does not support the following type arguments:

- Generic types
- Array of Godot Object (Godot.Object[]) or derived types

The new implementation uses delegate pointers to call the Variant
conversion methods. We do type checking only once in the static
constructor to get the conversion delegates.
Now, we no longer need to do type checking every time, and we no
longer have to box value types.
This is the best implementation I could come up with, as C# generics
don't support anything similar to C++ template specializations.
