  Create debug overlay for Site Isolation
https://bugs.webkit.org/show_bug.cgi?id=272908
rdar://problem/126701278

Reviewed by Alex Christensen.

This change creates a debug overlay for identifying frames and if
they are either local or remote. This is useful for matching what frames
are what when debugging sites with i-frames with site isolation on.

Currently this only draws for the local main frame and that process's view
of the other frames. Once we can support view overlays in i-frame processes
this can be expanded to show the current hosting process of each remote i-frame.
