  Metal: Add an in-memory MTLLibrary cache.
  
  Add a small cache for (msl + compile parameters) -> MTLLibrary at the
  egl::Display level. In regular executions of Chrome, the same shaders
  (particularly vertex) are compiled multiple times in different programs.
  
  Tested for a regular Chrome startup + open wikipedia + motionmark 1.2:
  112/282 (40%) cache hits.
  
  Several different caching methods were profiled (LinkProgram perf test)
   - struct key with std::map                             : 303309
   - struct key with std::unordered_map                   : 308090
   - binary blob key with std::map                        : 263595
   - binary blob key with std::unordered_map              : 286051
   - struct key + is_transparent with std::unordered_map  : 304877
   - struct key + is_transparent with absl::flat_hash_map : 335686
  
  Using is_transparent allows us to search the hash map without
  copying the shader source string to construct the key structure.
