Allow adding debug annotations to OpenGL objects, as well as defining GPU "zones" to achieve functionality very similar to Tracy, but on the GPU.

Implements #1833

Assists in assigning OpenGL id's to actual human readable names in performance debuggging.

IMPORTANT nVidia nSight 2022.04 was the only version that reliably worked for me.

New callouts:

• gl.ObjectLabel(objectTypeIdentifier, objectID, name)

  • Allows marking of buffers and shaders (and textures and pretty much anything else) with a label that is visible in GL call stacks.

• gl.PushDebugGroup(objectID, name, bool thirdparty = false)

  • To be used just like tracy.ZoneBeginN(name)

• gl.PopDebugGroup()

  • counterpart of tracy.ZoneEnd()

Results, with only some minor modifications to LuaShader.lua to label, push and pop things:

Unsure....
It doesn't compile and my comments seem to not have been addressed.
