std: remove an allocation in `Path::with_extension`
`Path::with_extension` used to reallocate (and copy) paths twice per call, now it does it once, by checking the size of the previous and new extensions it's possible to call `PathBuf::with_capacity` and pass the exact capacity it takes. Also reduce the memory consumption of the path returned from `Path::with_extension` by using exact capacity instead of using amortized exponential growth.
