Since we want to migrate to using GTEST_SKIP to skip unit tests instead
of GTEST_FILTER, we can remove the RestrictFilter() function which
filters the tests out using GTEST_FILTER. To do this, the RSAPerformance
test needs to be removed, which is acceptable since no one uses this
test anymore. However, b/299135804 is being used to track a new way to
either execute/track permance.
