Switch bitbake internals to use logging directly rather than bb.msg

We use a custom Logger subclass for our loggers

This logger provides:
- 'debug' method which accepts a debug level
- 'plain' method which bypasses log formatting
- 'verbose' method which is more detail than info, but less than debug
