Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that apache-arrow builds correctly, but only against
the default python version. Causing another package that could use more
than one python version to fail (dask).

To solve this, a number of changes needed to be applied:
- Patch calls to set_target_properties to use EXT_SUFFIX
- Update links in pyarrow-dev to point to the default version
- Build depend on python-all-dev
- Update test to run against the supported python versions

I applied these fixes in the sandbox [1] to be able to build the
packages that depend on apache-arrow, please consider applying the
patches to make it possible to build against multiple Python versions.

Happy hacking,
