[i-g-t 45/51] 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 with the above config (8K + ). Instead of
Skipping the test, we need to add some intelligence to identify
the valid combo to execute the test.
