libcamera: software_isp: Call Algorithm::configure

This patch adds Algorithm::configure call for the defined algorithms.
This is preparation only since there are currently no Algorithm based
algorithms defined.

A part of this change is passing IPAConfigInfo instead of ControlInfoMap
to configure() calls as this is what Algorithm::configure expects.
