shader: Implement EmitInvocationInfo across all backends

- Add proper invocation info handling for tessellation and fragment stages
- Return patch vertices info shifted by 16 bits for tessellation stages
- Return sample mask shifted by 16 bits for fragment stage
- Return standard format (0x00ff0000) for compute and other stages
- Implement consistently across SPIRV, GLSL, and GLASM backends
- Remove stubbed warning message
