Bug 1823694 - [lint.ruff] Disable some warnings we don't actually want to enforce, r=linter-reviewers,andi

This disables:
PLR0911     too-many-return-statements
PLR0912     too-many-branches
PLR0913     too-many-arguments
PLR0914     too-many-return-statements
PLR2004     magic-value-comparison

This removes nearly 2000 warnings.

This is enabling the PLE and PLC rules across a much larger swatch of the code
base. The PLR and PLW are additionally enabled at the warning level (introduces
~2500 new warnings).

To avoid extraneous changes in people's patches, rules at the warning level are
excluded from --fix.

Bug 1811850 - [lint] Replace isort linter with ruff, r=taskgraph-reviewers,linter-reviewers,marco,jcristau

This results in some changes from our current `isort` configuration. I'm
unclear if it's because ruff isn't at 100% parity with isort, they choose
different defaults or if I missed some configuration.

Either way, the changes all look reasonable to me (see child commit), so I'm
inclined to just accept the new import format it imposes.

Ruff is a very fast linter implemented in Rust and it can act as a drop-in
replacement for flake8. When running the same set of rules across all files
in mozilla-central (without mozlint), flake8 takes 900 seconds whereas ruff
takes 0.9 seconds.

Ruff also implements rules from other popular Python linters such as pylint,
isort and pyupgrade. There are even plans to implement feature parity with
black in the future. Ultimately, it can become our one stop shop for all Python
linting and formatting.

This stack will swap out all our Python lint tools for ruff (excluding black
for now).
