ipa: rkisp1: cproc: Store per-frame information in frame context

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.
