Bug 1733067 - Update SHEntrySharedParentState::mExpired when loading a page, r=peterv

The main part of the patch is to get the state to
CanonicalBrowsingContext::SessionHistoryCommit.
The old code does similar thing in
https://searchfox.org/mozilla-central/rev/d37daf2f82ed22b6a2a5cbbb975423825dfd69fa/docshell/base/nsDocShell.cpp#11630-11638

This is not fixing the issue with session store where the flag is lost.
Also, I think SessionHistoryEntry should probably store a timestamp and not just a flag, but that
would change the behavior more vs. the old implementation.
