[Feature]: Update to pyproject.toml

[Javagedes]

What does the feature solve?

Pip is deprecating and removing various functionality, one of which is not having a pyproject.toml or a setup.cfg file. This change has made it such that pip install -e . Does not work for local development of the repository. Switching to using pyproject.toml for project management and updating setup.py would resolve this issue.

Describe the solution

Switch to pyproject.toml and review other solutions for packaging edk2-pytool-extensions.
