ofproto: Move may_enable from ofport_dpif to ofport.

This concept of whether a port is suitable to be "live" in the sense of the
OpenFlow OFPPS_LIVE bit is a generic one that can be handled at the ofproto
layer instead of needing to be part of ofproto-dpif.

An upcoming commit will make more use of this at the ofproto layer.
