broadband-modem-mbim: implement profile management support

We use the "Provisioned Contexts" message support to add and edit
profiles.

We also use the same message, with context-type set to "none" to
attempt deleting it, although that doesn't seem to be fully supported
by all modems. E.g. the EM7345 (FIH7160_V1.1_MODEM_01.1349.12) will
still report contexts 'deleted' in this way, with the context-type set
to "none".º
