With the introduction of KUnit, IGT is no longer the only option to run
the DRM unit tests, as the tests can be run through kunit-tool or on
real hardware with CONFIG_KUNIT.

Therefore, remove the "igt_" prefix from the tests and replace it with
the "drm_" prefix, making the tests' names independent from the tool
used.

No strong feelings, but I wonder if having a prefix indicating it's a
test would be helpful to avoid any name clashes. As is, the drm_
prefixed names introduced here smell like regular drm functions, and
will also pop up in any code tagging tools such as cscope or GNU global.

BR,
Jani.
