ipa: Pass metadata to Algorithm::process() function

Browse source 
Extend the Algorithm::process() function with a metadata control list,
to be filled by individual algorithms with frame metadata. Update the
rkisp1 and ipu3 IPA modules accordingly, and drop the dead code in the
IPARkISP1::prepareMetadata() function while at it.

This only creates the infrastructure, filling metadata in individual
algorithms will be handled separately.
