[Site Isolation] Broadcast WindowScreenDidChange to remote frame processes
https://bugs.webkit.org/show_bug.cgi?id=321904
rdar://problem/185078141
Reviewed by Simon Fraser.
This fixes WebPageProxy::windowScreenDidChange() to broadcast the
WindowScreenDidChange message to
all of the page's processes rather than just the main frame's process.
There's another message above (PageScreenDidChange) which looks like it might
need to be broadcast
as well (it's used by the momentum dispatcher), but I'm not really sure. I left
a FIXME there and
will ping the layout and rendering team about it.
