Resource Load Statistics (experimental): Add fast mode for non-cookie website data deletion
https://bugs.webkit.org/show_bug.cgi?id=204858
<rdar://problem/57639851>

Reviewed by Alex Christensen.

Source/WebCore:

This change adds two internal flags:
- "Live-On Testing" with a one hour timeout instead of seven days.
- "Repro Testing" with an instant timeout (bar ITP's regular delays) instead of seven days.

These internal flags should be removed once testing is complete: <rdar://problem/57673418>

No new tests. This change just adds new opt-in settings for manual testing.

* page/Settings.yaml:
* platform/network/NetworkStorageSession.h:
    The FirstPartyWebsiteDataRemovalMode enum now has two new values:
    - AllButCookiesLiveOnTestingTimeout
    - AllButCookiesReproTestingTimeout

Source/WebKit:

The purpose of this change is to allow for dedicated testing of the change in
https://trac.webkit.org/changeset/253082/webkit. Waiting seven days just isn't a good
starting point.

This change adds two internal flags:
- "Live-On Testing" with a one hour timeout instead of seven days.
- "Repro Testing" with an instant timeout (bar ITP's regular delays) instead of seven days.

The change also makes sure that hasHadUnexpiredRecentUserInteraction() in
ResourceLoadStatisticsDatabaseStore and ResourceLoadStatisticsMemoryStore only
age out the user interaction timestamp if the OperatingDatesWindow is Long so
that we don't age out timestamps early with the shorter OperatingDatesWindows.

This change changes the default value of IsFirstPartyWebsiteDataRemovalEnabled to true.

These internal flags should be removed once testing is complete: <rdar://problem/57673418>
