Support substituting translated shaders.
Add dumpTranslatedShaders and enableTranslatedShaderSubstitution
frontend ANGLE features, which allow ANGLE developers to prototype
optimizations and other transforms without fully implementing them in
the shader translator.
Tested on macOS with ANGLE's Metal backend, but should work with the
other source-level translator backends.
Add documentation for pre-existing substitution of shader sources, and
of translated shaders added in this CL.
Fixed: angleproject:8280

GL: Fix ScalarizeVecAndMatConstructorArgs and move to gl/
This transformation was buggy and was disabled. Originally, it was
intended to be used everywhere. It is now needed for a GL driver
workaround.
This change reimplements this transformation and uses it as a GL
workaround.

Adds features to enable loading/saving metallibs to blobcache
CompileMetalShaders results in the appropriate command line tool
being run to generate metallib blobs from shader source.
DisableProgramCaching results in not saving programs to BlobCache
LoadMetalShadersFromBlobCache results in trying to load metallibs
from BlobCache.

Add features to dump and replace shader source.
dump_shader_source writes shader source strings to files named
with the hash of the source and shader type.
enable_shader_substitution allows subsituting the shader source
with the strings contained in a file. The same file naming scheme
as dump_shader_source is used so shaders can be dumped in one run,
modified and subsititued in the next run.
Use the ANGLE_SHADER_DUMP_PATH and debug.angle.shader_dump_path
environment variables to control where files are written. If they
are unspecified, write to the temp directory.
Based upon Cody's CLs:

Adding a class to perform ASTC texture decompression on the CPU
This significantly improves performance by caching and re-using the ASTC
decoder context, and using multi-threaded decompression.

Add a framebuffer fetch implementation of PLS
The framebuffer fetch implementation works by attaching PLS backing
textures to the framebuffer, and then rewriting PLS uniforms as "inout"
fragment variables. The compiler's existing machinery takes it from
there and makes it work on GL and Vulkan, and soon Metal.
EXT_shader_framebuffer_fetch is now the preferred backend for pixel
local storage, but we also use EXT_shader_framebuffer_fetch_non_coherent
if shader images can't be coherent. This is especially interesting for
Vulkan, since noncoherent framebuffer fetch is possible without any
extensions.

Add a GL_ANGLE_shader_pixel_local_storage extension
Plumbs through "GL_ANGLE_shader_pixel_local_storage" and
"GL_ANGLE_shader_pixel_local_storage_coherent" extension strings
advertised by ANGLE and stubs out an initial spec document. This change
doesn't add any new procedures or shader constructs, but it does allow
the PLS tests to start checking for the real extension strings and
requiring the GL_ANGLE_shader_pixel_local_storage extension.

Generate feature variable names from display names
The json file now only contains the feature display name. The variable
name is automaticaly derived.
For consistence with Chromium and other Chromium-based projects, the
display name is now always snake_case, and that's what's specified in
the json files. This also makes camelCase variable name generation
trivial (as opposed to the other way around).
Feature overrides now accept both snake_case and camelCase names to
ensure compatibility with existing scripts. This is done by removing _
and comparing override names with feature names in lower case.
