Remove build wheel script (#13308)

See mypyc/mypy_mypyc-wheels#45

Having the script in the main repo made it really hard to test changes
to the build. It also gets rid of annoying coupled changes, like
cibuildwheel version upgrades

+The main GitHub workflow where wheels are built:

-This uses cibuildwheel (https://github.com/pypa/cibuildwheel) to build the wheels.
-
-Usage:
-
-  build_wheel.py --python-version <python-version> --output-dir <dir>
-
-Wheels for the given Python version will be created in the given directory.
-Python version is in form "39".
-
-This works on macOS, Windows and Linux.
-
-You can test locally by using --extra-opts. macOS example:
+The script that builds wheels:
+https://github.com/mypyc/mypy_mypyc-wheels/blob/master/build_wheel.py
 
-  mypy/misc/build_wheel.py --python-version 39 --output-dir out --extra-opts="--platform macos"
+That script is a light wrapper around cibuildwheel. Now that cibuildwheel has native configuration
+and better support for local builds, we could probably replace the script.
