cpufreq/schedutil: Rewrite CPUFREQ_RT support

Instead of trying to duplicate scheduler state to track if an RT task
is running, directly use the scheduler runqueue state for it.

This vastly simplifies things and fixes a number of bugs related to
sugov and the scheduler getting out of sync wrt this state.

As a consequence we not also update the remove cfs/dl state when
iterating the shared mask.
