[issue39595] Improve performance of importlib.metadata and zipfile.Path

[Jason R. Coombs]

New submission from Jason R. Coombs <jaraco at jaraco.com>:

As reported in [jaraco/zipp#32](https://github.com/jaraco/zipp/issues/32), performance of zipfile.Path is inadequate. This bug tracks the incorporation of those improvements as well as those in [importlib_metadata 1.5](https://importlib-metadata.readthedocs.io/en/latest/changelog%20(links).html#v1-5-0).
