Update test for parsing memory access masks (#4703)

* Update test for parsing memory access masks

Needed to support SPV_INTEL_memory_access_aliasing extension

There is a negative test that checks unused mask bits.
Some of those bits are now sued by the new Intel extension.

* Update deps for new SPIRV-Headers
