<!-- Remember that you can run `/merge` to enable auto-merge in the PR
-->

<!-- Remember to modify the changelog. If you don't need to modify it,
you can check the following box.
Instead, if you have already modified it, simply delete the following
line. -->

Will be needed for enabling the fix for
https://github.com/paritytech/polkadot-sdk/issues/3144 (unbricking
paraids which acquire multiple cores via coretime). Will also be needed
in the future for enabling other features, like
https://github.com/paritytech/polkadot-sdk/pull/1644 and
https://github.com/paritytech/polkadot-sdk/issues/628
