commitablectx: add a class that will be used as a parent of mutable contexts

Currently, we have basectx that serves as a common ancestor of all contexts. We
will now add a new class commitablectx that will inherit from basectx and will
serve as a common place for code that will be shared between mutable contexts,
e.g. workingctx and memctx.
