<pre>[ThreadedCompositor] Move CompositingRunLoop class into a separate file
https://bugs.webkit.org/show_bug.cgi?id=156170
Reviewed by Michael Catanzaro.
Move the CompositingRunLoop class from the ThreadedCompositor.cpp file
into its own implementation file, with the class declaration placed
into the accompanying header file. This follows the general rule of
keeping different class implementations in separate files.
No change in behavior, just refactoring.
