Use GLSLANG_ANGLE to strip features to what ANGLE requires
This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.
