LOG: [mlir][spirv] Support SPIR-V 1.6 in deserializer (#151958)

After skimming through the changes in the spec, there does not seem to
be anything that will cause issues. A new roundtrip test has been added
and validate with `spirv-val` just in case.

Added: 
    

Modified: 
    mlir/lib/Target/SPIRV/Deserialization/Deserializer.cpp
    mlir/test/Target/SPIRV/module.mlir

Removed:
