ci/vc4: Skip VS dynamic loops tests that cause GPU hangs.
We've been getting spurious failures from the new VC4 CI, which I believe are due to this set of tests (which have been showing up along with a GPU hang report in the list of flaky tests in the failing jobs). This was a known issue I had in vc4. Reviewed-by: Jose Maria Casanova Crespo <email@example.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/7998>

# These are very slow
+# Conformance issue: VC4 needs dynamic loops in the VS to cause a
+# shader link failure.
+# The issue is that the HW doesn't have an exec mask at dispatch
+# for the VS, so the shouldn't-be-exec channels have undefined
+# contents and may cause infinite loops, leading to GPU hangs. The
+# process of GPU hang reset causes flakes in whatever other jobs are
+# running simultaneously, so we can't even leave these in the flakes
+# list for tracking.
