Camera: Support stream based flip

	Flip operation needs to be done per stream. App will read from system
	property about stream based flipping setting and set corresponding
	parameters to let camera hardware to apply flipping setting per stream.
	To keep app behavior persistent when flip and rotation are enabled,
	need to take case H/V flip when 90 or 270 rotation happens. Need
	to reverse H/V flip to acheive same output no matter device is in
	portait or landscape mode.
