This reduces the time needed to get to the first pixel on screen by multithreading the builtin shader compilation. We avoid doing this if subprocess compilation is on as the overhead of potentially partially starting all subprocess is far greater than the benefit of paralllel compilation. For some reasons, the compilation is much slower when done async for these shaders (on Metal ~200ms > ~1.2ms), so the saving might not be substantial. Mac M1: First frame 6s > 5s.
