wireproto: don't expose legacy commands to version 2 of wire protocol

Now that we have the ability to control which transports a wire
protocol command is exposed on, let's put it to use.

We flag the "branches," "changegroup," and "changegroupsubset"
commands as only available on version 1. "branches" was used by the
legacy discovery mechanism and was replaced by the "known" and
"heads" commands. "changegroup" and "changegroupsubset" were
replaced by "getbundle."

"between" is also legacy. However, since it is used by the SSH
handshake protocol, marking it as legacy is a bit more complicated
and will be done in a later commit.

Another nuanced issue with this change is that the server-advertised
capabilities still list "changegroupsubset" despite the command not
being available. This will be addressed in a subsequent commit.
