[PATCH v3 1/2] tests/kms_vrr: Add a subtest for seamless modeset to a virtual LRR mode

Hi Bhanu, Jani,
I do see that even the other vrr tests : seamless-rr-switch-vrr /drrs/
basic-fastset are getting skipped on BAT, so its not related to this
test. I am able to run it here locally and test.
Could you please take a look and see why all of these would be
skipped? Seems unrelated to this change.
Regards
Manasi
