  Fast copy R8G8B8A8_UNORM / R8G8B8A8_UNORM_SRGB for readPixels
  
  Support FastCopyFunction on R8G8B8A8_UNORM and R8G8B8A8_UNORM_SRGB.
  Copying src pixels to dest directly is more performant than converting
  UNORM to GLfloat.
  
  Bug: b/429541195
  Tests: dEQP-GLES31.functional.srgb_texture_decode.skip_decode*
