misc: update wheel building and release scripts (#9570)

* new upload pypi script

CI now builds the pure Python wheel and sdist.
Use the Github API to pull down all assets associated with the CI build.
Because this script now does very little, it's a lot simpler.
Since it's no longer building things, I assume we can be less picky
about what Python we use.
The version check now runs against the sdist, which is nice.

* update trigger wheel build for new wheel building

* remove more scripts

download-mypyc-wheels is now subsumed by upload-pypi, which uses the
Github API instead of hardcoding filenames.

test_installed_version is part of mypyc_mypy-wheels and some of what it
does is taken care of by cibuildwheel

* fix repo :-)
