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