libipa: FrameContext: Move init() to FrameContext

The FCtQueue structure initializes a new FrameContext using its init()
function. In case of request underrun, where a FrameContext is
initialized without application's controls being supplied, the
FrameContext needs to be initialized to default values.

In order to allow the single IPAs to initialize a FrameContext to
the desired default values, move the init() function to the FrameContext
structure, which each IPA derives to a per-IPA type.

In this way each IPA can override the FrameContext::init() function
and initialize the FrameContext to the desired default values.
