feat(shader): add compute shader support and refactor pipeline

Refactored shader system to support both graphics and compute shaders.
- Updated ANTLR grammars and parser logic for explicit shader model and compute shader entry points.
- Split shader models and descriptors for graphics and compute.
- Refactored pipeline key generation and D3D12 pipeline library for compute support.
- Updated push constant layouts and HLSL includes for both shader types.
- Improved error handling and test coverage with new example files.

BREAKING CHANGE: Shader model, descriptor, and pipeline APIs have changed. Existing shader and pipeline code must be updated to use the new types and conventions.
