Honor Cache-Control: public on unknown statuses
https://bugs.webkit.org/show_bug.cgi?id=317256
rdar://179870099
Reviewed by Chris Dumez.
Parse the Cache-Control: public response directive and allow it to make
responses storable even when
their status code is not cacheable by default. This lets such responses be
reused using heuristic
freshness (e.g. when they include Last-Modified).
RFC 9111 ยง3 defines public as an explicit storage condition:
