[i-g-t v7 0/8] tests/kms_vrr: Modify kms_vrr to allow flicker profiling

[Bhanuprakash Modem]

Do some cleanup in the kms_vrr test and add some optional command line
arguments to alter the target refresh rate for the test. This allows us
to profile VRR flicker on panels at the low end of the refresh range.
This series also adds a new 'maxmin' subtest which alternates the rate
between max and min every frame.

V2:
- Address the review comments from Bhanu
- Add a new maxmin subtest which alternates the rate b/w max & min every frame.

V3: As communicated in IRC channel #igt, I am doing this revision on behalf of
Sean Paul.
- Rebase
- Add testplan documentaion for 'maxmin' subtest
- Minor cleanups
- Hax patch to test VRR in BAT

V4:
- Rebase
- Minor cleanups

V5:
- Drop HAX patches to pass the CI
