Metal: Compile mtllib at build time. Reworks gen_mtl_internal_shaders.py to only generate the combined metal source file, mtl_internal_shaders_autogen.metal. metallibs are now compiled at build time using gn actions. This allows the Chrome and WebKit build process to use the same code for loading the builtin shaders even though they compile them in different ways. We now only build the mtllib for the OS we're currently building for.
