GH-110109: Speed up `pathlib._PathBase.resolve()` (#110412)

- Add fast path to `_split_stack()`
- Skip unnecessarily resolution of the current directory when a relative
  path is given to `resolve()`
- Remove stat and target caches, which slow down most `resolve()` calls in
  practice.
- Slightly refactor code for clarity.
