[PATCH v3 2/2] tests/intel/kms_frontbuffer_tracking: Enable the tests support variations based on the WAs

[Mohammed Thasleem]

This update stops skipping fbc-* tests support variations based on the WAs.

v2: Use WA_FBC_DISABLED instead CHECK_WA. (Vinod)
    Update igt_skip_on_f discription. (Vinod)
v3: Remove platform check and make it for xe specific. (Vinod)
    Rename function name with is_fbc_support. (Vinod)
