Arthur Paulino 6a67807fd0 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.

Arthur Paulino 01d9b61337 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.

Arthur Paulino f56d2f3bad `context.rs` enhancements
* Improve the phrasing of some docstrings and comments
* Add warning comments about attempts to validate memory addresses
  at reader/writer instantiation time
* Create the `reader_writer` method for ergonomically instantiate
  a reader/writer pair covering the same memory region. This method
  is also slightly more efficient than calling `reader` and `writer`
  separately
* Clean up `check_vaddr` for clarity and rename it to `check_vaddr_lowerbound`
  for explicity
* Include the data length check before calling `check_vaddr_lowerbound`
  in `atomic_load` and `atomic_fetch_update` for further consistency
  with the delayed buffer validation
