C#: Improve GD.PushError and GD.PushWarning
- Use the name, file path and line number of the caller that invokes
`GD.PushError` and `GD.PushWarning` instead of the location in the C++
`runtime_interop.cpp` file.
- Improvements to getting the C# stack trace.
  - Use C# type keywords for built-in types in method declarations.
  - Remove extra space before each parameter in method declarations.
  - Skip one more frame to avoid `NativeInterop.NativeFuncs`.
  - Skip methods annotated with the `[StackTraceHidden]` attribute.
- Improvements to `ScriptEditorDebugger` when source is in project.
  - Avoid overriding error metadata when the source is inside the
project file.
  - Use the source function in the title when the source is inside
the project file.

Users that use these methods would expect the reported location printed
by these methods to correspond to a location in their project source files.
Specifically, they'd expect to see the file path and line number at which
they call these methods, and not the location of the C++ code (which is
always the same). Now, these methods are a lot more useful since users
can know which line in their source code printed the error/warning.

How to build and run

  1. Build Godot with the module enabled: module_mono_enabled=yes.
  2. After building Godot, use it to generate the C# glue code:
    <godot_binary> --generate-mono-glue ./modules/mono/glue
    
  3. Build the C# solutions:
    ./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin
    

The paths specified in these examples assume the command is being run from the Godot source root.

How to deal with NuGet packages

We distribute the API assemblies, our source generators, and our custom MSBuild project SDK as NuGet packages. This is all transparent to the user, but it can make things complicated during development.

In order to use Godot with a development of those packages, we must create a local NuGet source where MSBuild can find them. This can be done with the .NET CLI:

dotnet nuget add source ~/MyLocalNugetSource --name MyLocalNugetSource

The Godot NuGet packages must be added to that local source. Additionally, we must make sure there are no other versions of the package in the NuGet cache, as MSBuild may pick one of those instead.

In order to simplify this process, the build_assemblies.py script provides the following --push-nupkgs-local option:

./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
    --push-nupkgs-local ~/MyLocalNugetSource

This option ensures the packages will be added to the specified local NuGet source and that conflicting versions of the package are removed from the NuGet cache. It's recommended to always use this option when building the C# solutions during development to avoid mistakes.

Double Precision Support (REAL_T_IS_DOUBLE)

Follow the above instructions but build Godot with the precision=double argument to scons

When building the NuGet packages, specify --precision=double - for example:

./modules/mono/build_scripts/build_assemblies.py --godot-output-dir ./bin \
    --push-nupkgs-local ~/MyLocalNugetSource --precision=double
