Switch code formatter to ruff

[Balandat]

Summary: Use the ruff code formatter. This diff

• Changes the Meta-internal config to use ruff.
• Updates pyproject.toml to use ruff as the code formatter.
• Applies the new formatting across the codebase.

This does NOT change the code sorting engine (that is still usort). We can update that in a next step.
