add SPIR-V 1.4 testing for no integer wrap decorations (#2041)

This PR adds targeted testing for SPIR-V 1.4 features. Specifically,
this PR adds testing for the NoSignedWrap and NoUnsignedWrap
decorations.

We can reuse large parts of the testing for the
`cl_khr_spirv_no_integer_wrap_decoration` extension to test the SPIR-V
1.4 feature.
