ipa: ipu3: Introduce modular algorithm

Implement a new modular framework for algorithms with a common context
structure that is passed to each algorithm through a common API.

This patch:
- removes all the local references from IPAIPU3 and uses IPAContext
- implements the list of pointers and the loop at configure call on each
  algorithm
- loops in fillParams on each prepare() call on the algorithm list
- loops in prepareStats on each process() call on the algorithm list
