[igt-dev] [i-g-t v5 23/52] tests/kms_plane_alpha_blend: Add support for Bigjoiner

[Bhanuprakash Modem <bhanuprakash.modem@intel.com>]

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.

V2: - Use updated helper name
V3: - Rebase
