[PATCH i-g-t v2 2/2] tests/xe_ccs: Update compression in config based on platform

[Akshata Jahagirdar]

In Xe2+ platforms, we need to run this test regardless of the status of
flat-ccs. The entore flow of the test should work even in case of flat-ccs
disabled, Everything should "just work".
Check if the platform supports compression and has flat ccs enabled, before
the execution if this test, and if it doesn't, then update to compression
disabled and proceed with the test.
