Removed: * NaN normalization * INFINITY normalization * errno normalization * Completely unused duration regex Tests using these macros should be tagged `[approvals]` so they are not run as part of approval tests. Also simplified regex for the test's executable filename, and hidden some tests relying on nullptr normalization.
