aic: Add IPU3 parameter encoder

The Parameter Encoder is imported from the ChromeOS implementation, with
some small changes to fit style and support building independantly.

The parameter encoders have assertions in them to check that the
required input data is valid. ispAwbFrEncode() is currently disabled
due to failing assertions around grid widths.
