controls: Split FrameDurations into FrameDuration and FrameDurationLimits

Browse source 
We need a separate control to report the nominal frame duration, but
it's also useful to report the min/max frame duration values that will
be used. Split the FrameDurations control into FrameDuration and
FrameDurationLimits respectively to support both of these.
