Support additional placeholders in ONC identity fields

Support additional placeholders in ONC identity fields such as Identity
or Username:
- CERT_SUBJECT_COMMON_NAME: the ASCII CommonName of the selected client
  certificate (replaced when a CertPattern is used).
- DEVICE_SERIAL_NUMBER: the serial number of the device. Only replaced
  in DeviceOpenNetworkConfiguration.
- DEVICE_ASSET_ID: the Asset ID of the device. Only replaced in
  DeviceOpenNetworkConfiguration.

This CL also changes ONC identity field variable replacement to use
|VariableExpander| instead of custom code.
