drm/panic: Compile KUnit tests as module

Fix dependency of the panic-helper KUnit tests on CONFIG_DRM_KUNIT_TEST=y
and make them build as a module. Export the necessary interfaces from the
panic helpers iff the KUnit framework has been enabled.

Select DRM_PANIC_HELPER from DRM_KUNIT_TEST to meet the dependencies of
the panic-helper tests.

It is now possible to run the tests by modprobe-ing drm_panic_helper_test
at runtime.

v5:
- clear test description with drm_panic_helper_clear_description() (Sashiko)
v3:
- clean up after each test case (Sashiko)
v2:
- fix parameter order in decl of drm_panic_helper_draw_screen_qr()
  (Sashiko)
