ipa: ipu3: Rework IPAFrameContext

Browse source 
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.
