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#: Add source generator for properties and exports default values The editor no longer needs to create temporary instances to get the default values. The initializer values of the exported properties are still evaluated at runtime. For example, in the following example, `GetInitialValue()` will be called when first looks for default values: ``` [Export] int MyValue = GetInitialValue(); ``` Exporting fields with a non-supported type now results in a compiler error rather than a runtime error when the script is used.

For example, in the following example, `GetInitialValue()` will be called when first looks for default values: ``` [Export] int MyValue = GetInitialValue(); ``` Exporting fields with a non-supported type now results in a compiler error rather than a runtime error when the script is used.

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#: 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.
