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: don't precompile default shaders.
Default shaders will be compiled from source at runtime, this is because
they depend on ANGLE format table and there is currently no way to
pre-compile metal shaders in a cross-platform manner.
Using default shaders' source instead of pre-compiled form seems to
reduce the libGLESv2's binary size. However, the startup time will be
increased due to runtime cost of compilation, thus the compilation now
will be done asynchronously.

Metal: Compile default shader source files separately.
- Previously all default shader files were included in one file named
master_source.metal.
- Now they will be compiled separately and link together to generate
binary shader.
- Also generate a debug binary variant that will be used in debug build.

Metal: draw 1 triangle instead of 2 for fullscreen shaders.
Reference article in favour of one big triangle instead of 2:
https://michaldrobot.com/2014/04/01/gcn-execution-patterns-in-full-screen-passes/
According to this article, the performance could be increased by ~10% for fullscreen shaders.
