Rework the algorithm's usage of the active state, to store the value of
controls for the last queued request in the queueRequest() function, and
store a copy of the values in the corresponding frame context. The
latter is used in the prepare() function to populate the ISP parameters
with values corresponding to the right frame.

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.
