Create python-cibuildwheel.yml

[hendrikmuhs]

switch the build system for python to cibuildwheel. cibuildwheel makes it easier to build python wheels on different platforms and python versions. The switch hopefully makes our life a little easier and lets us concentrate on the more important things.

With the switch we get:

• builds for mac on arm
• a new target: musllinux
• more pypy targets

In addition to the change I implemented the following additions in this PR:

• use of ccache per platform
• publishing of artefacts as part of the build (for testing PRs by installing the wheel locally)
• various toolchain updates, including enabling dependabot

@hendrikmuhs does this need to be reviewed, or I can turn off notification ?

@narekgharibyan sorry for the noise, I tested this out in the main repo. I have updated the description what this is about. It is not ready yet, but I am almost there.
