cmOutputConverter: Extract from cmLocalGenerator.

The Convert methods never belonged to the local generator concept, so
split them out now.  The cmOutputConverter is cheap to construct and
destroy, so it can be instantiated where needed to perform
conversions.  This will allow further decoupling of cmLocalGenerator
from the configure step.

Inherit cmLocalGenerator from cmOutputConverter for the purpose of
source compatibility.
