bitbake: toaster: models Remove LayerSource models and replace with enum

We had a lot of complexity around different layer sources to allow for
multiple sources and different priorities for these source. This was
implemented using rigged abstract classes which represented the
different layer sources when in fact just an enum/flag on the
layer_version object is sufficient for our needs.

Remove the LayerSourcePriority object as this is not needed. We no longer
have a problem of multiple layers coming from multiple sources so this
is not needed. Two migrations are added to first remove the child models
which represented layersources. Then a second migration is needed to
remove the LayerSource model it's self as Django can't understand the
non-standard base class dependency. Triggering this issue:

Clean up a number of flake8 warnings in classes which were modified.
