Added RecordUserAction.record() to avoid having to add a JNI call per UMA action

This CL:
- Adds RecordUserAction.record() and changes the UmaBridge callsites to
  use RecordUserAction.record() instead. This routes all of the UMA action
  recording through the same JNI call and avoids having to add a JNI call
  for each new user action.
- Modifies the extract_actions.py script to extract UMA actions for string
  literals parsed to RecordUserAction.record()
