ipa: ipu3: Rework IPAFrameContext
Currently, IPAFrameContext consolidates the values computed by the active state of the algorithms, along with the values applied on the sensor. Moving ahead, we want to have a frame context associated with each incoming request (or frame to be captured). This shouldn't necessarily be tied to "active state" of the algorithms hence: - Rename current IPAFrameContext -> IPAActiveState This will now reflect the latest active state of the algorithms and has nothing to do with any frame-related ops/values. - Re-instate IPAFrameContext with a sub-structure 'sensor' currently storing the exposure and gain value. Adapt the various access to the frame context to the new changes as described above. Subsequently, the re-instated IPAFrameContext will be extended to contain a frame number and ControlList to remember the incoming request controls provided by the application. A ring-buffer will be introduced to store these frame contexts for a certain number of frames.
