broadband-modem-mbim: use MBIMEx to list profiles unconditionally if available

We currently don't use the MBIMEx profile management operations by
default because the way profiles are managed is different (i.e.
profile id as index vs context type as index).

Still, when listing profile contents, we can use the MBIMEx operation
if supported, because it gives us much more information than the
original MBIM command, including IP type and profile source.
