broadband-modem-mbim: track uplink/downlink speeds only via indications

The uplink and downlink speeds will be exclusively tracked via packet
service indications, and stored within the MBIM modem object.

When the bearer connect result is built, we will include the latest
speeds reported, which may have changed upon the operation to connect
to the network.
