Fix MessageChannel with site isolation enabled
https://bugs.webkit.org/show_bug.cgi?id=293822
Reviewed by Sihui Liu.
In 255948@main we introduced a performance optimization to avoid IPC when a
MessagePort
is in the same process as its other port. However, with site isolation enabled
we don't
know that the MessagePort will continue to only be used in the same process so
this
performance optimization caused messages to be dropped when sent by the same
process that
created the MessageChannel. Skip the perf optimization when site isolation is
enabled.
This is one of at least 2 fixes needed to fix rdar://145004235
