manager: Split up new_wiphy dumps & events

Browse Source 
Separate out the two types of NEW_WIPHY handlers into separate paths and
factor out the common code into a utility function.

Dumps of CMD_NEW_WIPHY can be split up over several messages, while
CMD_NEW_WIPHY events (generated when a new card is plugged in) are
stuffed into a single message.

This also prepares ground for follow-on commits where we will handle the
two types of events differently.
