Compute Shader

[cpt-max]

This PR adds compute shader support for DirectX and OpenGL.
It's based on #7352 which already adds tessellation and geometry shaders.

The following use cases are covered (with sample projects):

• Fill up a StructuredBuffer in a compute shader, then use it directly in another shader stage (sample project)
• Fill up a StructuredBuffer in a compute shader, then download the data to the CPU (sample project)
• Write directly to a texture from a compute shader (2D texture sample, 3D texture sample)
• Write directly to a vertex or index buffer from a compute shader (sample project)
• Indirect drawing (simple sample, complex sample)

I finally updated the compute fork to the new MonoGame version (3.8.1).
The samples have been updated to .NET 6 and the new compute Nugets (3.8.2).
There's now also a Nuget for Android (MonoGame.Framework.Compute.Android) and some Android Samples.

A few more changes:

• Shader files that only contain shader model 2 and 3 shaders will now be compiled by MojoShader instead of ShaderConductor. Check the Shader Migration Guide for more details and a way to override this.
• Added integer surface formats, which can be used for per-pixel atomic operations.
• Assigning default values to shader parameters in HLSL will now also work for OpenGL. This is limited to assigning simple values though, no expressions or identifiers.
• Pixel shaders can now also write to buffers and textures (UAV) like compute shaders. This is DirectX only for now. With OpenGL that's possible too, but a bit more complicated.

Does this support Windows, Linux, Mac and Android + IOS?

i not saw IOS, so does it not?

There's this link from my first post: NuGet Packages, Platform Support and Build Requirements
A few posts up I'm also talking about iOS: #7533 (comment)

@cpt-max can you put up a sponsor button ill hit it.

@damian-666 I don't really want to do that. Once I start taking peoples money, I'll feel obligated to deliver something in return. While I have no plans to stop supporting the compute fork, it's just a spare time project for me, not business.

I published new MGCB Nugets. This fixes an issue where content wasn't built, when building from within the MGCB editor.
The new version is 3.8.2.3. This affects the Nugets that go into dotnet-tools.json

Solved some merge conflicts and updated to new MG version with .NET 8 support. New NuGet version is 3.8.3.
