Switch to pyproject.toml-based build

[ejm714]

setup.py commands have been deprecated, so let's move to a pyproject.toml based build

Bonus fixes

• use the "paths" option to tell mkdocstrings where to find modules instead of installing the package. This makes the test matrix run about 10 min faster overall.
• pip install pytorchvideo instead of using direct reference

The error in the CI failure

No module named build

needs

python -m pip install --upgrade pip build

instead of

python -m pip install --upgrade pip setuptools wheel

[ejm714]

python -m pip install --upgrade pip build

Another option is to do pip install -r requirements-dev.txt as build is contained there and will install everything needed for the tests. Any preference @jayqi?

[jayqi]

I don't have a strong preference there. Given that that part of the workflow only runs the build and doesn't run the tests, it would be faster if it didn't need to install dependencies that aren't needed for building.

[ejm714]

@jayqi this is ready for your review now

Looks good. Just one note about the link names.
