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.

Metal: Use shared memory for small dynamic buffers.
- If BufferMtl is static or large size, don't use shadow copy. Use one
MTLBuffer and map directly on it.
- If BufferMtl is dynamic and small size, use shadow copy and buffer
pool of 10 MTLBuffer (s). The MTLBuffer is allocated in shared memory
in this case (PCI-E memory for example). MTLBuffer in shared memory
region doesn't need to sync content between CPU and GPU.
- When copyBuffer, if BufferMtl is being used by GPU use blit command to
do the copy on GPU side.
- Also implemented GL_MAP_UNSYNCHRONIZED_BIT.
