fix(Visual): add SRP support on CameraColorOverlay

[Wolar]

Probably related to https://github.com/ExtendRealityLtd/VRTK/issues/1959 so I didn't open a new issue.

I didn't test the actual functionality, so code review only.

No problem with that change, should be changed now

We're friends of the idea of "once a PR is merged the commits it brought should be primarily helpful for the readers of the commits". As such we'd like you to squash the commits before we merge (whether we merge is pending someone else to review). So just squash and force-push! (GitHub thankfully has good UX for reviewing force-pushes even.)

Ok, no problem, done

I just found out that this solution is not enough for Quest. For some reason I'm getting

OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_OPERATION: Operation illegal in current state
(Filename: ./Runtime/GfxDevice/opengles/GfxDeviceGLES.cpp Line: 353)

I've tried to replace that GL rendering code in PostRender with something like code bellow for SRP
var cmd = CommandBufferPool.Get("FadeScreenPass"); cmd.SetViewProjectionMatrices(Matrix4x4.identity, Matrix4x4.identity); cmd.DrawMesh(RenderingUtils.fullscreenMesh, Matrix4x4.identity, workingMaterial); cmd.SetViewProjectionMatrices(sceneCamera.worldToCameraMatrix, sceneCamera.projectionMatrix); context.ExecuteCommandBuffer(cmd); CommandBufferPool.Release(cmd); context.Submit();

but it didn't help and I can't figure out how to fix this / fixing this is beyond my skills.

This should be fixed now
