[Site Isolation] Storage access not cleared when cross-site iframe is removed
https://bugs.webkit.org/show_bug.cgi?id=307358
rdar://169986015
Reviewed by Sihui Liu.
When site isolation is enabled and a cross-site iframe with storage access
is removed from the DOM, the storage access entry was not being cleared. This
happens because WebPage::frameWasRemovedInAnotherProcess (in site isolation),
which calls WebFrame::removeFrameTree, which actually removes the storage
access for frames.
The fix adds the proper clean up when a frame is removed in another process.
