Notifies can_read property changed.
If Efl.Io.Reader.can_read is true
there is data to Efl.Io.Reader.read without blocking/error. If Efl.Io.Reader.can_read is false
, Efl.Io.Reader.read would either block or fail.
Note that usually this event is dispatched from inside Efl.Io.Reader.read, thus before it returns.
