libcamera: software_isp: Initialize exposure+gain before agc calculations
On my setup, since commit fb8ad13d ("libcamera: software_isp: Move exposure+gain
to an algorithm module"), at start camera output stays very dark for dozen
of seconds, and then later slowly gets to normal. This is because existing
sensor exposure+gain settings are not used at start. We save initial
values in frameContext but in the agc algorithm we use IPA context.
Fix the problem by using in frameContext sensor values, since we already
use those in blc algorithm and change exposure type to int32_t to
unnecessary castings.
