libcamera: software_isp: Create algorithms

Browse source 
We are ready to introduce algorithms now.  First, let's create
algorithms.  The algorithms are not called yet, calls to them will be
added in followup patches.

The maximum number of contexts is set to the same value as in hardware
pipelines.
