Add support for path dependencies (#471)

Browse source 
## Summary

This PR adds support for local path dependencies. The approach mostly
just falls out of our existing approach and infrastructure for Git and
URL dependencies.

Closes https://github.com/astral-sh/puffin/issues/436. (We'll open a
separate issue for editable installs.)

## Test Plan

Added `pip-compile` tests that pre-download a wheel or source
distribution, then install it via local path.
