Add API to request Bug Report with a certain title and description

ActivityManagerService will send the details to dumpstate and
BugreportProgressService will get the details from dumpstate and use
that for the notification.

Bug: 33561517
Test: Modify TelephonyMonitor to use this API and ensure that the
      notification uses that the title and description sent as arguments
      to the API. File a bug using betterBug and ensure that the
      information gets populated automatically.
