Allowing useStillCameraForTimeLapse to be set through MediaRecorder.java

This will allow apps to make the decision of whether to use still image mode or
video mode for time lapse capture.

- setTimeLapseParameters now takes in a useStillCameraForTimeLapse parameter.
- Added support in StagefrightRecorder for passing through this parameter.
