[i-g-t 22/51] tests/kms_plane: Add support for Bigjoiner

[Bhanuprakash Modem]

This patch will add a check to Skip the subtest if a selected pipe/output
combo won't support Bigjoiner or 8K mode.

Example:
* Pipe-D wont support a mode > 5K
* To use 8K mode on a pipe then consecutive pipe must be available & free.
