libipa: FCQueue: Initialize FrameContext with activeState

Pass to the FCQueue the algorithm's active state to use the most
recent state of IPA algorithms to initialize a FrameContext.

Modify all IPA modules that use libipa to pass a const ActiveState
reference to the FCQueue function and make their IPAActiveState
implementation derive a base ActiveState structure.
