Subject: aiq: Provide initial Intel AIQ Wrapper support

The AIQ class is the entry point for running IPA algorithms for the
requested frame and handles the statistics being generated. It comprises
of wrapping the ia_aiq_*_run() functions and provide helper functions
that take in the input parameters and location for their results after
the run. These results(AiqResults) can be used for subsequent runs and
setting statistics as required.
