ipa: libipa: Add frame context pointer in process()

Browse source 
Currently we have a single structure of IPAFrameContext but
subsequently, we shall have a ring buffer (or similar) container
to keep IPAFrameContext structures for each frame.

It would be a hassle to query out the frame context required for
process() (since they will reside in a ring buffer) by the IPA
for each process. Hence, prepare the process() libipa template to
accept a particular IPAFrameContext early on.

As for this patch, we shall pass in the pointer as nullptr, so
that the changes compile and keep working as-is.
