Try enabling Swift IPC layout test
https://bugs.webkit.org/show_bug.cgi?id=304433
rdar://166293273

Reviewed by NOBODY (OOPS!).

This commit endeavours to enable a Swift CoreIPC message receiver test on a
very small permutation of platforms:

* Debug or ASAN or anything else where IPC tests are explicitly enabled;
* MacOS only;
* The most recent SDKs only.

Any such EWS builders matching that description will then run the layout
test in a mode where a Swift CoreIPC receiver is tested. This will be the
first time any builder has built any Swift into the main WebKit target.

It's possible that no builders yet exist matching this description, or
that only Apple internal builders match this description.

Though, please of course fix the issue impacting the mac-apple queue :)

The Apple internal queue is failing here because we need to wait for our SDKs to absorb the fix for swiftlang/swift#84816.
