[Kokoro] Add dxc-smoketest (KhronosGroup#6113)

New validation check in spir-val can identify invalid code generated by DXC.
This will generally only be caught when DXC or SPIR-V tools is imported into
Google3. This can take a while. Adding the smoke test will enable us to get an
early warning that DXC needs to be updated.
