[igt-dev] [v5] tests/i915/kms_dsc: Validate dsc with diff plane formats

[Swati Sharma]

Already existing subtest is modified so that dsc can be validated
using different plane modifiers. Few 8/10/16 bpc RGB and YUV formats
are added.

v2: -minor fixes
v3: -renaming
    -addition of new planar format test
v4: -removing XRGB8888 from format_list
    -test name managed with single var
v5: -changed MIN_BPP to DSC_MIN_BPP
