cxxrtl: s/sync_{wire,type}/edge_{wire,type}/. NFC.

The attribute for this is called (* cxxrtl.edge *), and there is
a planned attribute (* cxxrtl.sync *) that would cause blackbox
cell outputs to be added to sync defs rather than comb defs.
Rename the edge detector related stuff to avoid confusion.
