  [Site Isolation] Fix broken frame tree traversals in BackForwardCache::trySuspendPage
https://bugs.webkit.org/show_bug.cgi?id=287834

Reviewed by BJ Burg and Alex Christensen.

Remove a local frame early return and fix recursive functions so that they visit local frames that have
remote parents. No change in behavior while bfcache or site isolation is disabled.
