Implement nested Dedicated Workers

https://bugs.webkit.org/show_bug.cgi?id=22723
<rdar://6425810>

Reviewed by Darin Adler.

Add support for nested dedicated workers. Blink and Gecko already support this.

Also fix an issue where ScriptExecutionContext were added too early to the ScriptExecutionContextMap.
This was marking calls to postTaskTo() unsafe since it would call the virtual postTask() function
on a ScriptExecutionContext that had potentially not finished construction. This was causing flaky
test crashes.
