Fix an issue with the background page trying to message full page extension
content
https://bugs.webkit.org/show_bug.cgi?id=272362
rdar://125996453
Reviewed by Timothy Hatcher.
When an extension was trying to send a message from a background page to a tab
with full page extension content, we were treating
the message as going to a content script and sending it to a non-main world,
which led to a crash.
Additionally, we want to block an extension from sending a message to a tab
showing full page content for a different extension. One
extension should have no idea about another's content.
