Sean Feng 7a83be92b8 Bug 1863246 - Make the page that enters BFCache not asking the parent process to update the active browsing context r=peterv,dom-core a=RyanVM
Currently, when a page enters BFCache, it updates the parent process
for the active BC; however, the page that is about to show will do the
same. These two operations are triggered in different processes with
different active id, they are racy and problematic.

This patch fixes the above issue by not updating the parent process
when a page enters BFCache.

This only applies to BFCacheInParent is enabled.
