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. Signed-off-by: Shahbaz Youssefi <ShabbyX@gmail.com>
