ipa: rkisp1: Rename frameContext to activeState

Browse source 
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.
