This reverts commit f8e8fcf8.

Reason for revert: ANGLE_SKIP_TEST_IF doesn't work in perftests
and this skip is not needed since the whole suite is disabled now

Original change's description:
> Suppress crashing perftests on Win Intel Exp Rel
> 
> Also moves ANGLE_SKIP_TEST_IF to a header shared between end2end and
> perf tests.
