Unsplit wheel builds now that we have an index

[bdraco]

Proposed change

We should not hit the memory limit anymore now that we have an index.

However since memory usage is not always exactly the same, and other changes will affect it, there may still be a specific wheel that needs the split though, but we can't tell for sure until it actually happens.

If it turns out we still are hitting the limit in the future, we can revert (or switch to a 2 part split) this PR when/if that happens.

This was successful but we are still building wheels we probably shouldn't be

I'm not sure pip is the latest version on the wheel builder

needs to be retested once #100646 (comment) is sorted

Let's remove the splitting 👍

Happy to see that workaround go away

[bdraco]

The split is sometimes faster which is likely because of pip getting slower with a higher number of packages pypa/pip#12314

I've been sitting on this one because I wanted to see the outcome of the above issue as it might make sense to keep them split until that gets solved

Going to close this for now, until things get resolved upstream.

Cleaning up the queues a bit, to gain a better overview of our open PR queue.
