  Metal: Implement parallel shader linking.
  
  Update the Metal library cache to be thread safe. Change
  absl::flat_hash_map back to std::unordered_map because the value types
  now contain a mutex which must not move.
  
  Only generate async compilation tasks for shaders that were not already
  compiled and in the cache.
  
  Collapse some of the link methods in ProgramMtl that only had one call
  site. All linking is now done in ProgramMtl::link and
  ProgramMtl::load.
  
  Support disabling parallel linking using the new
  enableParallelMtlLibraryCompilation feature.
