libcamera: software_isp: Call Algorithm::queueRequest

This patch adds Algorithm::queueRequest call for the defined algorithms.
As there are currently no control knobs in software ISP nor the
corresponding queueRequest call chain, the patch also introduces the
queueRequest methods and calls from the pipeline to the IPA.

This is preparation only since there are currently no Algorithm based
algorithms defined and no current software ISP algorithms support
control knobs.
