[Clang][HLSL] Fix invalid flag passed by the driver (#170300)

Keenuts · web-flow · commit 734a912d0f02 · 2025-12-02T16:35:25.000+01:00
The test were using the DXC driver in Clang, which adds the
`--spirv-ext=` option. Turns out some buildbots are built without this
flag support, meaning any test using this driver would fail with an
'unknown command line argument' error.
