Move string uniquing tables to (new) WTFThreadData class.

Reviewed by Sam Weinig.

Remove AtomicString's dependency on ThreadGlobalData so that we can move
WebCore's string classes up to WTF.

JavaScriptCore:

WTFThreadData.cpp/.h are based on ThreadGlobalData from WebCore.
Moved JSC & WebCore's string uniquing tables to this class.

This patch introduces a temporary layering violation in providing forward
declarations of classes from JSC and WTF; this will be resolved as we move
more string code up to WTF.
