[igt-dev] [PATCH i-g-t v2] tests/i915/gem_ctx_exec: Skip test for RCS+CCS

[priyanka.dandamudi at intel.com]

From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

The test tries to submit non-preemptible spinners to all engines,
causes a hang and expects the non-preemptible spinners to survive
but fails to do for RCS+CCS.
So, updated the code to skip nohangcheck subtest for a platform with RCS+CCS.
