This PR implements a Metal backend for macOS. It should bring better performance compared to Vulkan, as well as fix some issues that wouldn't be possible with Vulkan due to MoltenVK limitations. I haven't tested many games, but those that I tried worked pretty well.

TODO:

  • sRGB
  • fix low resolution
  • proper present
  • fix black textures in sm3dw
  • buffer copies in a vertex shader
  • pipeline cache with binary archives
  • geometry shaders
  • GamePad screen in a separate window
  • fix texture readback
  • output shader
  • ImGui
  • Intel Macs support
  • proper surface copy
  • extend the shader hash
  • triangle fans
  • 1D shadow sampler emulation
  • instancing with mesh shaders
  • occlusion queries
  • async shader compilation
  • load pipeline binaries at startup
  • async pipeline compilation
  • accurate occlusion queries
  • binary archives
  • fix CI
