[Feat] (ProgramState): Implement automatic GLSL uniform management.

Browse Source 
- Add SPIRV-Cross/glslang integration for uniform reflection.
- Auto-detect and assign locations for uniforms/samplers.
- Support most types of uniform.
- Implement glUniform* functions with type safety.
- Add MG_Util::Program:
  - GLSL-SPIRV conversion
  - SPIRV uniform reflection
  - Program uniform dumping
