[Document Policy] Isolate font-display wpt tests

This CL splits font-display tests into smaller individual tests. The
split has following benefits:

- Clear obstable for implementation of violation report deduplication
- Make the tests stricter. Before the test can verify there are
4 violation reports generated, but cannot tell which 4 cases generate
violation reports.

Previously there was an attempt on isolating tests into subframes
(https://chromium-review.googlesource.com/c/chromium/src/+/2227863),
but failed due to flaky crash in network cache (crbug.com/1087277).
