[IndexedDB] Fix request reentry in IndexedDBDatabase

During ForceClose, a closing connection could cause the active request
to 'complete', triggering the rest of the requests to execute. Since
the connections are cleared after-the-fact in ForceClose(), this caused
a UAF.

Instead having specialized weakptr factories here, this change creates
a |force_closing_| variable which is set in ForceClose(), which is used
to ensure reentry doesn't occur.
