Metal: Adding alternative support for GPU_PRIM_TRI_FAN/LINE_LOOP For Metal backend.

- Metal uniform array compatibility in DRW module.
- Guard OpenGL-specific workarounds and flushes behind GPU_type_matches_ex API guard. Add further render boundaries for render paths called outside of the main loop.
