[CI] Move build-wheels to Orange repository

[PrimozGodec]

Issue

Building wheels in separate repository require more manual work. Sorry, @ales-erjavec, for moving away from your wheel repo.

Description of changes

I am moving wheel building here since this change can trigger wheel building by making a release (now an extra commit is required). Also, cibuildwheel settings are moved to pyproject.toml

This PR also makes some other improvements:

• Wheels are loaded in the release as assets
• Wheels are automatically uploaded to PyPI
• No requirement to manually build source (tar.gz) anymore
• Faster wheel building since it is redistributed among several workers (for each wheel)
• Stop building wheels for Python 3.8.

Note about the removed test (and file): elftools, which is used as a part of autditwheel on Linux, changed behaviour in how they recognize ELF file (not necessary to have complete header anymore). binary-blob.tab looks like an ELF file with an incomplete folder, so it reads it but fails later and breaks the audit process. Since binary-blob.tab is no longer used in tests with Python 3.11, we can remove it earlier to avoid problems. The problem started to paper with cibuidwheel 2.10 (previously, we built wheels with cibuildwheel 2.9).

TODO: when merged, a Trusted publisher must be added to PyPI.
