Implement PLS on Apple Silicon
Implements a subset of EXT_shader_framebuffer_fetch in the Metal
translator that is sufficient to support pixel local storage. Metal's
"programmable blending" feature is available on all Apple family GPUs
beginning with version 2.
Support for non-Apple GPUs will come later via readWrite textures,
which can also be coherent by annotating them with
[[raster_order_goup(0)]].

Translator: Make vec/matrix size getters unsigned
TType stored type's primary and secondary sizes as `unsigned char`, but
the getters returned `int`. This caused unnecessary casts when the size
was passed from one TType to another, as well as comparisons with other
unsigned numbers.
This change specifies the type of these members as `uint8_t` and makes
the getters return the same type. The call sites are accordingly
adjusted to remove unnecessary casts, use the correct type in local
variables, and add casts when passed to ostream::operator<<.

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.
