[PATCH V3 0/3] rust: Introduce CpuId and fix cpumask doctest

[Viresh Kumar <viresh.kumar@linaro.org>]

Hello,

Here is another attempt at fixing the cpumask doctest. This series creates a new
abstraction `CpuId`, which is used to write a cleaner cpumask example which
doesn't fail in those corner cases.

Rebased over v6.16-rc1 + [1].

V2->V3:
- Include the separately sent patch as 3/3 and clarify about `unstable` CpuId.
- Add few debug_assert!().
- Improved comments, commit log.

V1->V2:
- Introduce CpuId.
- Use CpuId in cpufreq, opp, cpumask abstractions.
- Fix cpumask example.
