Port SPIRV-Reader kernel-arg-qual workaround

To update opencl-clang in IGC a newer SPIRV-Translator is needed.
This is currently not possible, since SPIRV-Translator removed writing
"const" kernel func arg qualifier to *.spv as NoWrite param,
since this was not correct with the SPIR-V spec.
A workaround has been created and this change
ports it from SPIRV-Translator to IGC's baked-in SPIRV-Reader:
