Redesign the setPreferredNetworkType

Some APPs(like OMA DM) might enable or disable 5G settings, so redesign
the setPreferredNetworkType behavior.

1. Create allowed_network_type in telephonyprovider
2. Create get/set allowed network type API
3. When APPs call setPreferredNetworkType() that will AND with allowed
network type.

Bug: 136730709
Test: By Manual
1. setAllowedNetwork to disable 5G
2. setPreferredNetworkTypeBitmask to set NR_LTE_GSM_WCDMA
3. framework set LTE_GSM_WCDMA to modem
