wireproto: move version 2 command handlers to wireprotov2server

This is relatively straightforward.

As part of this, we introduced a local @wireprotocommand that
wraps the main one and defines a v2 only policy by default.

Because the hacky HTTPv2 peer isn't using capabilities response
yet, we had to move some code around to force import of
wireprotov2server so commands are registered. This is super
hacky. But this code will go away once the HTTPv2 peer is using
the capabilities response to derive permissions.
