wireprototypes: convert `baseprotocolhandler.name` to an abstract property

PyCharm was flagging the subclasses where this was declared as a `@property`
with

    Type of 'name' is incompatible with 'baseprotocolhandler'

But pytype didn't complain.  This seems more correct, however.  Since `Protocol`
is already an `abc.ABCMeta` class, we don't need to mess with the class
hierarchy.
