Describe the feature you'd like

Building the Python wheel is kinda messy. Especially when it comes to cross-compilation.
The current setup.py will likely only work if host == target.

In our CI (using cibuildwheel) it sometimes doesn't pass --plat_name to bdist_wheel which we inject then.
See:
https://github.com/capstone-engine/capstone/blame/5e6807bab9ba6a8112b8ba1f92285924e699ee84/bindings/python/setup.py#L205-L211

This is of course not ok and probably breaks at some point. So we should put the effort into it and clean the whole thing up.

This is closely related to removing the Makefile build. Since the bindings partially rely on it (optionally via pkgconfig.mk).
