ipa: rkisp1: Rename frameContext to activeState
The RkISP1 IPA module creates a single instance of its IPAFrameContext structure, effectively using it more as an active state than a per-frame context. To prepare for the introduction of a real per-frame context, move all the members of the IPAFrameContext structure to a new IPAActiveState structure. The IPAFrameContext becomes effectively unused at runtime, and will be populated back with per-frame data after converting the RkISP1 IPA module to using a frame context queue. The IPAActiveState structure will slowly morph into a different entity as individual algorithm get later ported to the frame context API. While at it, fix a typo in the documentation of the Agc::computeExposure() function that incorrectly refers to the frame context instead of the global context.
