Implement `IdSet::iter_in`
...
This patch enables more expressive ways to slice and iterate over
the `Id`s in an `IdSet` with `IdSet::iter_in`, which takes an arbitrary
`IdSetSlicer`.
`IdSet::iter_in` efficiently slices out unintended inner parts and
then, within the remaining parts, skips inactive bits by using
`BitSlice::iter_ones` from the `bitvec` crate.
It also delivers several implementations of `IdSetSlicer` so OSTD
consumers can represent `Id` ranges ergonomically.
In the Asterinas kernel, `CpuSet::iter_in` enables a cleaner way to
define an interator that cycles over the CPUs.

Enhanced per-CPU load stats
...
This patch creates a `PerCpuLoadStats` with slightly enhanced, enough
to serve load stats and the load-balancing algorithm. This struct can
be further enhanced for more elaborated load-balancing algorithms in
the future.
The load stats report has been fixed, as `SchedulerStats::nr_queued_and_running`
no longer includes idle threads in the queued total nor in the running
threads.
Furthemore, the load-balancing algorithm has been improved because it
no longer accounts with the idle threads when they're enqueued.
