port-qmi: add support for QMAP data aggregation

We now allow requesting for multiplex support in the set data format
operation of the MMPortQmi.

If multiplexing is supported, we'll configure both the modem (link
layer protocol and data aggregation protocol) and the kernel expected
data format (if qmi_wwan in use).

The logic adds additional preferences over the different choices we
may find in the logic:
  * In newer modems, by default QMAPv5 is preferred over QMAP as data
    aggregation protocol.
  * If using qmi_wwan, by default rmnet (qmap-pass-through) is
    preferred over add_mux/del_mux (raw-ip) kernel expected data
    format.

These preferences are only considered if the specific support is found
in the setup.

Whenever we change the multiplexing support, an internal port reset
operation will be run, in order to bring the state of the setup to a
clean known one.
