Move blobalizer implementation to ShapeResultBloberizer

Move blobalizer implementation to ShapeResultBloberizer

Move blobalizer logic out of CachingWordShaper and ShapeResultBuffer and
into ShapeResultBloberizer, thereby containing all blobalizer logic in a
single file and removing dependencies on it from the results and shaper.

This will also help in reusing much of the text blob logic for LayoutNG.

FYI, this is a pure refactoring - no functionality changes.

Next step is adding support for blobarizing ShapeResults directly which should
be trivial. After that we can add support for drawing NGTextFragments :)
