drm/tests: helpers: rename generic helpers

The creation of a dummy device in order to test managed interfaces is a
generally useful test feature. The drm test helpers
drm_kunit_helper_alloc_device() and drm_kunit_helper_free_device()
are doing exactly this. It makes no sense that each and every component
which intends to be testing managed interfaces will create similar
helpers so rename these to more generic format.
