Changes in v4:
- Keep existing IdPool constructor (renamed to with_capacity).
- Undo docs changes that were due to the removal of the existing IdPool
  constructor.
- List id < pool.map.len() as invariant for UnusedId and mention it in
  as_u32() comment.
- Fix [`acquire`] docs links.
- Link to v3: https://lore.kernel.org/r/20251028-binder-bitmap-v3-0-32822d4b3207@google.com

Changes in v3:
- Also update documentation to fix compile errors.
- Use new_inline() instead of new_small().
