WIP: Enhance shader compilation performance and control

This commit adds new settings and optimizations for shader compilation:

- Add new settings:
  - use_enhanced_shader_building: Enable enhanced shader compilation
  - shader_compilation_priority: Control shader compilation priority

- Improve shader compilation performance:
  - Optimize worker thread allocation based on CPU cores
  - Add smarter async shader compilation heuristics
  - Prioritize vertex and fragment shader compilation
  - Add performance tracking and logging

- Add performance monitoring:
  - Track shader compilation times
  - Log slow shader compilations
  - Monitor async shader compilation statistics

This is a work in progress commit. Further optimizations and refinements
will be needed based on testing and feedback.
