Merge WTFThreadData to Thread::current

Use Thread::current() instead.

Source/WTF:

We placed thread specific data in WTFThreadData previously. But now, we have a new good place
to put thread specific data: WTF::Thread. Before this patch, WTFThreadData and WTF::Thread
sometimes have the completely same fields (m_stack etc.) due to initialization order limitations.
This patch merges WTFThreadData to WTF::Thread. We apply WTFThreadData's initialization style
to WTF::Thread. So, WTF::Thread's holder now uses fast TLS for darwin environment. Thus,
Thread::current() access is now accelerated. And WTF::Thread::current() can be accessed even
before calling WTF::initializeThreading.
