Start building armv7l wheels (#1127)

<!-- Thank you for your contribution! -->

## What do these changes do?

Copy the wheel build changes from `yarl` to use `armv7l` which also
splits the `manylinux` and `musllinux` jobs which means the release
process will be a bit faster

~~Note that the `manylinux` `armv7l` wheels might still not build and we
will than have to add the exclude like we do for `yarl` since the
previous `manylinux` image for `armv7l` did not have a working `cffi`
package. In theory this has been fixed in
https://github.com/pypa/cibuildwheel/releases/tag/v2.23.0~~ yarl
released fine with manylinux now

## Are there changes in behavior for the user?

`armv7l` wheels
