[igt-dev] [i-g-t V2 46/52] tests/i915/kms_frontbuffer_tracking: Add support for Bigjoiner

[Bhanuprakash Modem]

As many 2x tests are currently running on Pipe-A & B only, those
tests will always SKIP if there is any 8K supported panel in the
config. Instead of Skipping the test, add some intelligence to
the subtest to identify the valid pipe/output combo to execute
the subtest.
