[PATCH v4 12/18] libcamera: software_isp: Call Algorithm::process

[Milan Zamazal]

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

As software ISP currently doesn't produce any metadata, a dummy and
unused metadata instance is created to satisfy Algorithm::process API.
This should be changed in future.
