bundle2-push: move changegroup push validation inside _pushb2ctx
When bundle2 push includes more than just changesets, we may have no
changegroup to push yet still have other data to push.
So we now try to performs a bundle2 push in all cases. The check for changegroup
inclusion is moved into the ``_pushb2ctx`` function in charge of creating the
changegroup part.
The bundle2 part is aborted if no actual payload part have been added to the
bundle2.
