Camera2: Adds support for longshot/burst mode

- The longshot/burst pipeline mode uses an
  optimized path for triggering 'takePicture()'
  on each shutter callback. This should improve
  the shot-2-shot time. In addition to this
  there is also support for jpeg callbacks
  that only contain a jpeg file path. The
  callback in this case will only move the
  file stored by the lower layers in the
  correct directory.
- The longshot burst pipeline can be enabled
  via this property:
  "persist.camera.longshot.enable"<-"0/1"
- This change will allow longshot mode to
  be triggered in non-zsl mode as well.
