Enhancement - Pathlib Support for Tools

Pathlib is a modern Python library for handling filepath/pathing and has been part of the standard Python library since approximately 2014 (Python 3.4). More than a decade later, my hope is that ArcPy be enhanced to accept Paths as inputs.

Currently, as of ArcGIS Pro 3.4, the utilization of Paths creates a runtime error which could be difficult for new ArcPy users to decipher; the workaround is to wrap all paths in a `str()` function. This is doable but clutters up development. The alternative is to do things the old-fashioned way with strings only which is a bummer.

This enhancement request is to provide the necessary functionality for file inputs as `pathlib.Path` type.
