AOSP/Messaging - update the Messaging version to target P (28) or higher.
Use JobIntentService to start the Backgroundworkerservice and
ActionServiceImpl services.

+ Deleted WakeLock code.
+ Made changes to com.android.messaging.test tests so that all tests
  pass with the new JobService. I am not sure if these tests passed
  before these changes.
+ CTS tests passed without any changes.
+ Added TEST_MAPPING file for presubmit tests.
