Reviewed by Darin Adler.

Adds a script for determining what feature defines (ENABLE, USE, HAVE)
are present in portions of WebKit code. As an example the script can
search all native code for all `ENABLE(flag)` and report back a full
listing. In addition it can also find differences between sections of
code which can be used to find stale build options.

* Tools/Scripts/find-feature-flags: Added.
* Tools/Scripts/webkitpy/featuredefines/__init__.py: Added.
* Tools/Scripts/webkitpy/featuredefines/matcher.py: Added.
* Tools/Scripts/webkitpy/featuredefines/matcher_unittest.py: Added.
