ci: enable arm64/aarch64 wheel builds

[nikaro]

Migrate wheel build system from multibuild to cibuildwheel to enable builds for ARM64 OSes.

Follow-up of #3430 ping @mpenkov

@nikaro Any idea why uploading takes 1.5 hours (in comparison to building, which takes 20 min)?

That's weird, i don't see why the Windows upload takes so much time for seven files when it takes only ~20 minutes for eight files under Ubuntu. And this step did not change 🤔

I wonder if a separate and unique upload job (that would grab the artifacts for all three platforms) wouldn't be more efficient.

PS: I see that someone from gensim already opened an issue regarding a similar issue, cf. ogrisel/wheelhouse-uploader#31

Might also be simpler to rewrite the upload code using boto3... what do you think?

Actually, GitHub runners come with AWS CLI installed so it should be even more straightforward to just use aws s3 sync ./wheelhouse s3://gensim-wheels (cf. https://docs.aws.amazon.com/cli/latest/reference/s3/sync.html).

In the meantime, i pushed this PR, and it works and has the advantage also to provide the wheels as GitHub artifacts (see at the bottom of the workflow summary page). Replacing wheelhouse-uploader by aws s3 sync should be very simple, but i don't have an AWS playground to test it.
