ipa: ipu3: Use sensor controls to update frameContext

The pipeline handler populates the new sensorControls ControlList, to
have the effective exposure and gain values for the current frame. This
is done when a statistics buffer is received.

Make those values the frameContext::sensor values for the frame when the
EventStatReady event is received.

AGC also needs to use frameContext.sensor as its input values and
frameContext.agc as its output values. Modify computeExposure by passing
it the frameContext instead of individual exposure and gain values.
