Update license information for Scala dependencies to Apache v2
Scala, Scala XML, and Scala Parser Combinator libraries all relicensed
from BSD-3 to Apache v2. This means we no longer need to maintain
separate license information in the LICENSE and bin.LICENSE files, but
need to copy the NOTICE information into NOTICE and bin.NOTICE.

This makes the appropriate LICENSE/NOTICE changes, updates the Apache
Rat config to no longer need a special case for the Scala license, and
updates to the latest Apache v2 licensed version of UniquenessCache.
