[Intel-gfx] [PATCH] tests/kms_psr_sink_crc: Adding test debug options

[Rodrigo Vivi]

Just to make life easier and be eable to easily test with
PSR disabled to know exactly what to expect when running it
for real

v3: Use igt_debug helpers and add env option for running with psr disabled
on this test without have to recompile like v1 or changing igt infrastructure like v2.
I tried to add --disable-psr or local --dry-run but than it fails to print subtests
so this was the safest way.
