Add Python autoformatter

[multiplemonomials]

Summary of changes

This PR adds an autoformatter for Mbed OS's python scripts. This makes sure that they all have consistent formatting, and will make development easier going forward.

Note: I did not make any manual modifications to python scripts as part of this PR. Everything that was changed was done by Ruff. The only files that need to be reviewed are:

• .github/workflows/basic_checks.yml
• tools/pyproject.toml
• tools/run_python_linters.sh

Unfortunately this docker container still has an ancient Python version (3.8, I think), so I doubt it would support the latest versions of tools like Ruff. We really need a new version of this container, but that's really not something I am excited to do, so for now I had to make these jobs not use the container.

I think this would look much better as a single line instead of a couple dozen. It's small enough to fit with 120 characters, which means that this formatting was due to the magic trailing comma.

I think you should re-run formatting with skip-magic-trailing-comma enabled (and then disable it and re-run ruff format), though I would also suggest combing through the changes since some magic trailing commas appear to be beneficial.

I would be OK to pass on that if you thought that it would require too much effort or discretion.

Oddly, adding that setting did not cause any changes to be made. However, I can fix this line at least.

[VictorWTang]

Did you add this to your pyproject.toml?

[tool.ruff.format]
skip-magic-trailing-comma = true

I enabled the setting and it reformatted 77 files.

Ah, I think I got confused and thought the default was true so I set it to false X_X. Now it worked, done!
