Upstream Apple's direct-to-Metal backend: compile translator. This change is meant to merge the translator 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 translator code in a state that compiles, but not to switch the Metal backend over to use this translator backend yet.
