ipa: raspberrypi: agc: Fix digital gain calculation for manual mode
The digital gain calculation uses a total exposure value computed with the
current AGC state. However, this is wrong in the case of manual shutter/gain
controls, as the total exposure value used must be the value computed when the
AGC sent the manual shutter/gain controls to the pipeline handler to action.
To fix this, the IPA now adds the historical AgcStatus structure to the metadata
(tagged with "agc.delayed_status"). This historical AgcStatus structure contains
the total exposure value calculated when the AGC sent the manual shutter/gain
controls to the pipeline handler.
