Added DeviceAdminInfo to dumpsys device_policy.

Also included missing fields, like mHeadlessDeviceOwnerMode.

For example, using TestDpc as DO, it would show:

  Enabled Device Admins (User 0, provisioningState: 0):
    com.afwsamples.testdpc/.DeviceAdminReceiver:
    ...
       mProvisioningContext=null
      DeviceAdminInfo:
        mVisible: true
        mUsesPolicies: 991
        mSupportsTransferOwnership: true
        mHeadlessDeviceOwnerMode: 1
