Manually generate HLSL skip files for vk-gl-cts e2e tests

It seems we haven't run our e2e tests with FXC validation in a long time
 - at least not since we've added the vk-gl-cts corpus.

Locally disabled exclusion of "/test/vk-gl-cts/" in test-runner/main.go,
and ran:
./test/test-all.sh out/build/x64-Debug/tint.exe --format hlsl --fxc --generate-skip

These will need to be manually removed once the skips aren't needed by
deleting them all, and re-running as above.
