ipa: raspberrypi: awb: Better handling of how we disable AWB
We now handle disabling ("pausing") AWB in the same way as AEC/AGC. Instead of letting the pause flag be set so that the code never runs at all, we instead fix the manual settings to the current values (but continue to be called). The algorithm does not restart any calculations in this state, but continues to add AWB metadata to every frame. Therefore certain other algorithms that want to know it (CCM and ALSC, for example) can still find it.
