Camera2: Prevent propogating CancelAutoFocus during Video Recording

When AutoFocus is started during Video Recording, CancelAutoFocus
is called after KEY_FOCUS_TIME seconds. CancelAutoFocus has the
side effect of resetting the sensor AF position and will result in
instant loss of focus which is not a desired event when AF is
manually triggered in case of Video Recording.

Camera: Move out TimeLapse option from global list

TimeLapse setting was common for front and back camera
As there is no specific reason to have it common, to align with
other settings, moved it out from common list so that Timelapse
setting change in front camrea will not affect for back camera
and vice versa.
