WifiBackupRestore: Parse older backup data
Add a new API to restore the old backups containing the raw data
from wpa_supplicant.conf & ipconfig.txt files.
Changes in CL:
1. Migrate all the wpa_supplicant.conf parsing logic in
|SettingsBackupAgent| into |WifiBackupRestore|.
2. Create WifiConfiguration objects from the wpa_supplicant.conf.
3. Parse the ipconfig data using |IpConfigStore| into
IpConfiguration objects.
4. These retrieved networks are added back using addOrUpdateNetwork().
While there,
1. Make the "id_str" parsing/writing methods in WifiNative static so that
it can be used for restoring the data from wpa_supplicant.conf.
2. Make all the configurations enabled & shared in the test
WifiConfiguration objects.
