[igt-dev] [PATCH i-g-t 2/2] tests/frontbuffer_tracking: Assert the status of other features on stridechange subtest

[José Roberto de Souza]

As explained in c1edee186d18 ("tests/frontbuffer_tracking: Do not
assert FBC state after a page flip changing stride") after changing
the plane stride there is the possibility that CFB will not be big
enough to keep FBC enabled, that is why do_assertions() is called
with DONT_ASSERT_FEATURE_STATUS but DONT_ASSERT_FEATURE_STATUS is
overkill and will not check the status of the other features like PSR
and DRRS when running combined feature tests and possibly hiding
bugs.

So lets add a new flag that will only not assert FBC.
