Source/WTF:

Simplify main thread initialization on macOS by always using pthread main as main thread.
The complexity is now isolated to the USE(WEB_THREAD) code path.

This patch also adds a debug assertion in WTF::initializeWebThreadPlatform() to make sure
it gets called on the actual main thread. In release, it will log a fault message indicating
it was called on the wrong thread.
