Add C# source generator for a new ScriptPath attribute This source generator adds a newly introduced attribute, `ScriptPath` to all classes that: - Are top-level classes (not inner/nested). - Have the `partial` modifier. - Inherit `Godot.Object`. - The class name matches the file name. A build error is thrown if the generator finds a class that meets these conditions but is not declared `partial`, unless the class is annotated with the `DisableGodotGenerators` attribute. We also generate an `AssemblyHasScripts` assembly attribute which Godot uses to get all the script classes in the assembly, eliminating the need for Godot to search them. We can also avoid searching in assemblies that don't have this attribute. This will be good for performance in the future once we support multiple assemblies with Godot script classes. This is an example of what the generated code looks like: ``` using Godot; namespace Foo { [ScriptPathAttribute("res://Player.cs")] // Multiple partial declarations are allowed [ScriptPathAttribute("res://Foo/Player.cs")] partial class Player {} } [assembly:AssemblyHasScripts(new System.Type[] { typeof(Foo.Player) })] ``` The new attributes replace script metadata which we were generating by determining the namespace of script classes with a very simple parser. This fixes several issues with the old approach related to parser errors and conditional compilation. It also makes the task part of the MSBuild project build, rather than a separate step executed by the Godot editor.

C#: Make GodotSharp API a NuGet package In the past, the Godot editor distributed the API assemblies and copied them to project directories for projects to reference them. This changed with the move to .NET 5/6. Godot no longer copies the assemblies to project directories. However, the project Sdk still tried to reference them from the same location. From now on, the GodotSharp API is distributed as a NuGet package, which the Sdk can reference. Added an option to `build_assemblies.py` to copy all Godot NuGet packages to an existing local NuGet source. This will be needed during development, while packages are not published to a remote NuGet repository. This option also makes sure to remove packages of the same version installed (~/.nuget/packages). Very useful during development, when packages change, to make sure the package being used by a project is the same we just built and not one from a previous build. A local NuGet source can be created like this: ``` mkdir ~/MyLocalNuGetSource && \ dotnet nuget add source ~/MyLocalNuGetSource/ -n MyLocalNuGetSource ```
