bitbake/msg.py: Drop manually created domain lists

This patch removes the majority of the domain related code from bb.msg
on the grounds that we now support dynamic creation of logging domains
so having this hardcoded is just error prone and less flexible. It also
makes the msg code overly and needlessly complex.

It also removes the bb.msg.debug/note/warn/plain/error functions since
we might as well remove them rather than try and fix them at this point.
