  Upstream Apple's direct-to-Metal backend: compile libANGLE.
  
  This change is meant to merge the metal backend changes from Apple's
  direct-to-Metal backend. Taken from Kyle Piddington's CL:
  https://chromium-review.googlesource.com/c/angle/angle/+/2857366/
  The goal of this CL is to merge the metal backend code in a state
  that compiles, but not to switch the Metal backend over to using
  the direct-to-metal backend yet.
