ipa: ipu3: Put IPAFrameContext(s) in a ring buffer
Instead of having one frame context constantly being updated,
this patch aims to introduce per-frame IPAFrameContext which
are stored in a ring buffer. Whenever a request is queued, a new
IPAFrameContext is created and inserted into the ring buffer.
The IPAFrameContext structure itself has been slightly extended
to store a frame id and a ControlList for incoming frame
controls (sent in by the application). The next step would be to
read and set these controls whenever the request is actually queued
to the hardware.
Since now we are working in multiples of IPAFrameContext, the
Algorithm::process() will actually take in a IPAFrameContext pointer
(as opposed to a nullptr while preparing for this change).
