Unified PSO validation semantics across D3D12 and OpenGL backends:
- IsValid() returns whether PSO is ready to use
- EnsureValid() ensures PSO is valid (compiles if needed)
Behavior by backend:
- D3D12: IsValid=false after creation, true after EnsureValid() with shaders
- OpenGL: IsValid always=true (immediate model)
Also added test_pipeline_state.cpp with 10 tests for RHIPipelineState.
- Add ShaderLanguage enum (HLSL, GLSL, SPIRV)
- Extend ShaderCompileDesc with source/sourceLanguage fields
- D3D12Device::CompileShader supports both file and embedded source
- OpenGLDevice::CompileShader supports embedded GLSL source
- Refactor test_shader.cpp to use embedded source for both backends
This enables consistent shader compilation across D3D12 and OpenGL
backends while maintaining backend-specific shader language support.

GetCompletedValue() semantics: returns the highest confirmed completed value,
not the last Signal() target value. When Signal(5) -> Signal(3),
GetCompletedValue() should still return >= 5 since GPU already completed that.
