toaster: orm Remove the layerindex specific up_branch fields

We don't need to keep track of layerindex data in our database. And
using branch==release is very confusing in the schema. Instead use the
existing Release definition to keep track of which release a
layer_version is for.

Remove the Branch model and all references to it.

Create a migration path to convert from up_branches to their
corresponding releases.
