According to https://www.apache.org/legal/src-headers.html#faq-binaries
all our released source packages and binaries should have both LICENCE
and NOTICE files - even if we do not have any 3rd-party software embedded.
This PR updates it accross the board and makes sure that all our
distributions contain both LICENCE and NOTICE file and that they
are added as "licence" information to all our distribution packages
when they are built.
This PR also modernizes all our pyproject.toml files with regards
to latest metadata for licenses:
* license-file is an array of glob patterns
* license is s license expression
* the deprecated Trove Classifier is removed
Inspired by #58131
