Parquet/Feather IO: disable PyExtensionType autoload
Similar to https://github.com/apache/arrow/pull/38608, but doing it on our side as well for people that use latest pandas with older pyarrow. 
(using a similar approach as https://github.com/pitrou/pyarrow-hotfix, without adding a required dependency on that package)
Can you add a whatsnew? Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
git checkout 2.1.x
git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
git cherry-pick -x -m1 851fea0ea38985cd7d5e0a3b7a7a7539b5883307
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
git commit -am 'Backport PR #55894: Parquet/Feather IO: disable PyExtensionType autoload'
```

4. Push to a named branch:

```
git push YOURFORK 2.1.x:auto-backport-of-pr-55894-on-2.1.x
```

5. Create a PR against branch 2.1.x, I would have named this PR:

> "Backport PR #55894 on branch 2.1.x (Parquet/Feather IO: disable PyExtensionType autoload)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the `Still Needs Manual Backport` label once the PR gets merged.
