CI: checkout repo before dependency cache step

actions/cache's hashFiles('pyproject.toml') was returning empty because
pyproject.toml was not present in the workspace. Add actions/checkout
before the cache steps in build_wheels and build_wheels_emulated_linux
so the cache key includes the dependency version hash.
