Description

In this PR, I migrated from setup.py to pyproject.toml using uv.
Fixes #3327.

In detail I did followings:

• migrate setup.py features to equivalent pyproject.toml
• introduce uv as a package manager
• move dependency configurations for test from tox.ini to pyproject.toml
• update tox version to use new features of tox and pyproject.toml

A part of codes are burrowed from @dlstadther 's branch.
ref master...dlstadther:luigi:migrate-setup-to-pyproject

Motivation and Context

python setup.py install is deprecated.

Have you tested this? If so, how?

CI worked.
