core: new '--test-mbimex-profile-management' option

The profile management APIs implemented by Microsoft in the MBIM
extensions provide certain features that are not available via other
means (e.g. ip type, access type preference, roaming allowance...).

Unfortunately, these APIs require the current list of profiles
installed in the modem to be a bit special; e.g. with one profile max
for each context/APN type. If this does not happen, the operations
will fail, or they will update contexts that should not be updated.

So, we disable for now the MBIM extension profile management support;
the logic is there, but not used by default.
