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).
