There is no longer need to perform all the CID selection logic in the
broadband bearer connection procedure, we can rely on the new profile
management operations to do the same thing.
We can do this because we're sure that all the MMBroadbandModem
objects implement the MMModem3gppProfileManager interface.
Additionally, given that we now provide the profile ID value as part
of the MMBearerConnectResult, we no longer need a custom
mm_broadband_bearer_get_3gpp_cid() as we can use the generic
mm_base_bearer_get_profile_id() for the same purpose.
The new helpers allow converting a PDP context list returned from the
+CGDCONT? parser to a list of 3GPP profile objects.
The new mm_3gpp_profile_list_find_best() method is equivalent to the
mm_3gpp_select_best_cid() one, but using profile objects as
input/output instead of specific settings.
The unit tests that were testing mm_3gpp_select_best_cid() are also
converted to use mm_3gpp_profile_list_find_best().
There is no point in providing a configurable default IP family in the
bearer object, because we can always assume IPv4 as being the only
default expected.
Simplify the logic and also provide a new method to get the normalize
the IP family, using IPv4 as default always.
The ModemManager1.Sim.PreferredNetworks property contains the preferred
networks (and access technologies, if available) configured to the
SIM card.
This commit implements preferred networks reading with AT+CPOL.
Instead of blindly assuming that we can take whatever string given as
valid UTF-8, we'll always attempt to convert from the current modem
charset into UTF-8. Before we were doing this for hex-encoded UCS2,
but not for example for GSM-7.
And due to the now applied GSM-7 conversion, the mf627a/mf627b +COPS
parsing unit tests are updated accordingly, because when converting
from an input string that contains byte 0x40 ('@' in UTF-8) as if it
were GSM-7, the 0x40 is taken as character '¡', encoded as 0xc2,0xa1
in UTF-8).
All BCD-encoded strings used by MM currently have the low nybble
of each byte come before the high nybble, but some strings (such
as the EID string returned by QMI Get Slot Status) are meant to
be read in order with the high nybble before the low one. As such,
extend mm_bcd_to_string to decode both.
So that we avoid errors when building on ARM due to increasing target
type alignment.

This fixes the s8500 wave unit test, which was incorrectly parsing the
Act field reported as 'B' as "GSM" (strtol(B)=0)
Also, given that the generic parsing methods are able to parse numbers
from quoted strings, this change allows us to remove the Thuraya
specific CREG matching that just took into consideration quoted
strings. The Thuraya unit tests are also fixed up to provide proper
testing of the logic.

If the charset selected via CSCS is UCS2, the modem may decide to
return all the strings in the +COPS=? response in UCS2:

Rework how the broadband bearer runs CGDCONT? and CGDCONT=? and setup
a helper method to perform the CID selection logic.
Also, implement unit tests for the CID selection logic.
