Qualcomm has added another WFC preference setting `IMS Preferred`
which is not supported in AOSP. If we let carriers default to this
setting, the AOSP settings app shows that WFC is disabled and
`Unexpected WFC mode value: 10` is logged. Even though the default
mode is still working fine, the user is unable to change to this
mode again once a different mode was selected. To fix this, remove
all default WFC mode settings with value "10" and let these carriers
default to "2" (`WiFi Preferred`, the default in AOSP) instead.
Leave the `carrier_wfc_supports_ims_preferred_bool` configs in place,
such that, in case the following patches are present in the system,
the user is still able to select the `IMS Preferred` mode in settings
manually.

Additionally, enable the WFC mode settings for the affected carriers
which didn't enable them before such that the user can still prefer
cellular calls over vowifi without disabling vowifi completely.
