Currently, 304 responses do not set the CORP header, which seems to be
the correct behavior according to
https://datatracker.ietf.org/doc/html/rfc7232#section-4.1
On the other hand this causes issue because we incorrectly consider
that the cached request did not set CORP, and ends up being blocked by
COEP, which is definitely not an appropriate behavior.
This introduces a WPT verifying the behavior, and does some minor
cosmetic changes to the test it's based upon.
