C#: Add initial implementation of source generator for script members This replaces the way we invoke methods and set/get properties. This first iteration rids us of runtime type checking in those cases, as it's now done at compile time. Later it will also stop needing the use of reflection. After that, we will only depend on reflection for generic Godot Array and Dictionary. We're stuck with reflection in generic collections for now as C# doesn't support generic/template specialization. This is only the initial implementation. Further iterations are coming, specially once we switch to the native extension system which completely changes the way members are accessed/invoked. For example, with the native extension system we will likely need to create `UnmanagedCallersOnly` invoke wrapper methods and return function pointers to the engine. Other kind of members, like event signals will be receiving the same treatment in the future.

C#: Static marshaling for bindings and source generators Previously, we added source generators for invoking/accessing methods, properties and fields in scripts. This freed us from the overhead of reflection. However, the generated code still used our dynamic marshaling functions, which do runtime type checking and box value types. This commit changes the bindings and source generators to include 'static' marshaling. Based on the types known at compile time, now we generate the appropriate marshaling call for each type.

C#: Array, Dictionary and marshaling refactoring - Array and Dictionary now store `Variant` instead of `System.Object`. - Removed generic Array and Dictionary. They cause too much issues, heavily relying on reflection and very limited by the lack of a generic specialization. - Removed support for non-Godot collections. Support for them also relied heavily on reflection for marshaling. Support for them will likely be re-introduced in the future, but it will have to rely on source generators instead of reflection. - Reduced our use of reflection. The remaining usages will be moved to source generators soon. The only usage that I'm not sure yet how to replace is dynamic invocation of delegates.

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.

Support for them also relied heavily on reflection for marshaling. Support for them will likely be re-introduced in the future, but it will have to rely on source generators instead of reflection. - Reduced our use of reflection. The remaining usages will be moved to source generators soon. The only usage that I'm not sure yet how to replace is dynamic invocation of delegates.

C#: Static marshaling for bindings and source generators Previously, we added source generators for invoking/accessing methods, properties and fields in scripts. This freed us from the overhead of reflection. However, the generated code still used our dynamic marshaling functions, which do runtime type checking and box value types. This commit changes the bindings and source generators to include 'static' marshaling. Based on the types known at compile time, now we generate the appropriate marshaling call for each type.

C#: Array, Dictionary and marshaling refactoring - Array and Dictionary now store `Variant` instead of `System.Object`. - Removed generic Array and Dictionary. They cause too much issues, heavily relying on reflection and very limited by the lack of a generic specialization. - Removed support for non-Godot collections. Support for them also relied heavily on reflection for marshaling. Support for them will likely be re-introduced in the future, but it will have to rely on source generators instead of reflection. - Reduced our use of reflection. The remaining usages will be moved to source generators soon. The only usage that I'm not sure yet how to replace is dynamic invocation of delegates.

C#: Fix exported properties of GodotObject[] type This was a regression from 17b2838f39c634324710166d2f36458906ecaf4a. `MarshalUtils` was changed in the source generators to use `ConvertTo<T>` and `CreateFrom<T>`, which don't support `GodotObject[]` because it would need reflection. As such, we need to keep the custom cases for `GodotObject[]` in `MarshalUtils`.

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.

C#: Cleanup Variant marshaling code in source/bindings generators This change aims to reduce the number of places that need to be changed when adding or editing a Godot type to the bindings.

The only exceptions are the generic Godot collections (`Array<T>` and `Dictionary<TKey, TValue>`) which still use the old version, as that one cannot be matched by our new conversion methods (limitation in the language with generics, forcing us to use delegate pointers).

C#: Add initial implementation of source generator for script members This replaces the way we invoke methods and set/get properties. This first iteration rids us of runtime type checking in those cases, as it's now done at compile time. Later it will also stop needing the use of reflection. After that, we will only depend on reflection for generic Godot Array and Dictionary. We're stuck with reflection in generic collections for now as C# doesn't support generic/template specialization. This is only the initial implementation. Further iterations are coming, specially once we switch to the native extension system which completely changes the way members are accessed/invoked. For example, with the native extension system we will likely need to create `UnmanagedCallersOnly` invoke wrapper methods and return function pointers to the engine. Other kind of members, like event signals will be receiving the same treatment in the future.
