Python 3.11 support

[jrbourbeau]

Python 3.11 has been released 🎉 Historically it has taken some time for our dependencies to add support for new Python versions and for those changes to show up in releases. Opening this issue for tracking purposes

cc @charlesbluca in case this is something you might be interested in

Right now, the current blockers to solving a 3.11 environment are:

• tiledb-py constraint set in Restrict tiledb-py version to avoid CI failures  #9569
  • it suffices to set tiledb-py!=0.17.5, but not sure if we've tested CI with newer versions
• numba builds for 3.11 (migration being tracked in Python 3.11 numba/numba#8304)
• numcodecs builds for 3.11 (required by zarr, being tracked in Release 0.11 with Python 3.11 support zarr-developers/numcodecs#377)
• libprotobuf pin set in CI: pin libprotobuf to allow nightly pyarrow in the upstream CI build #9465

These are optional right? Maybe they can be dropped from the Python 3.11 CI environment for now and added back later once they have Python 3.11 support

Thanks for the write up @charlesbluca!

Yeah, that seems totally fine by me (and what we've done in the past). It looks like @graingert is taking that approach over in #9708

This should now be addressed.
