Support PEP 561 to all packages

[Kludex]

This issue tracks work on supporting PEP 561 on the opentelemetry-python-contrib packages.

Important

• Having Add type checker #3116 merged, or an alternative proposed would help us a lot here.

Notes

1. opentelemetry-instrumentation already has a py.typed, but it's missing a lot of type hints. I've opened Improve type hints in opentelemetry.instrumentation.utils #3128 to help a bit there, but we need a type checker to be more efficient.
2. Add type checker #3116 contains the ty.typed for threading and the type checker PR. Happy to separate if wanted.

I was asked to stop creating PRs till some are reviewed.

I'll wait for some to be reviewed before continuing.
