Android updates

[mhsmith]

• Add Python 3.14 support, including downloading official binaries from python.org.

• Simplify update_pythons.py:

  • Remove the redundant Windows arch setting.
  • Unify Config classes which are now identical.
  • Make the new config replace the old config rather than merge with it. This makes the behavior easier to reason about.

• Update to latest versions of Python 3.13 and 3.14:

  • CPython's android.py script now automatically configures KVM on GitHub Actions, so cibuildwheel users no longer need to do that manually.

• Don't assume that patchelf will be on the PATH (#2552).

FYI, if it helps at all, currently we just read the groups out and pass them as requirements, but we can probably move to using the --groups option at some point now that pip and uv support it.

There are a few more things I want to deal with, but they're all connected to testing wheels, so I think I'll put them in a separate PR.

Should we consider this the start of 3.2?

[mhsmith]

I'm not exactly sure what the version number policy is. There's nothing backward incompatible about this PR, but it does add a new platform / Python version pair.

Looks good to me. I'll have a look at the other PRs regarding the versioning question...

The current PR queue feels like we're heading to 3.2 at this point.
