ipa: rpi: agc: Split AgcStatus into AgcStatus and AgcPrepareStatus

Browse source 
The Agc::process() function returns an AgcStatus object in the
metadata as before, but Agc::prepare() is changed to return the values
it computes in a separate AgcPrepareStatus object (under the new tag
"agc.prepare_status").

The "digitalGain" and "locked" fields are moved from AgcStatus to
AgcPrepareStatus.

This will be useful going forward as we can be more flexible about the
order in which prepare() and process() are called, without them
trampling on each other's results.
