drm/i915/selftests: Hide dangerous tests

Browse Source 
Some tests are designed to exercise the limits of the HW and may trigger
unintended side-effects making the machine unusable. This should not be
executed by default, but are still useful for early platform validation.

This option enables the execution of selftests that are "dangerous"
and may trigger unintended HW side-effects as they break strict
rules given in the HW specification. For science.
Recommended for masochistic driver developers only.
