Start gcam module directly when handling capture intent.

Bug: 11609971

- Prior behavior for capture intents when in HDR+ mode was
  to resume into the PhotoModule and switch to the GcamModule.
  Following this change, we resume directly into the GcamModule.

- Fixes the bad lockscreen behavior caused by the sequence:
  onResume->switch to GcamModule(queue GcamModule onPause and onResume)->
  onPause->onResume, where handler queuing order could get in a
  state where the GcamModule onResume is called twice in a row,
  resulting in duplicate requests being queued for each capture.
