This fixes the keyboard navigation for the actions cell when the first (or all) button is disabled.
It does also introduce a new check for the managesOwnFocus and renames it to canManageOwnFocus

Couldn't test this, the CSB build links don't work. Do you have a CSB we can test this in?

Open question, if the focus is on the cell to the right and the user presses "left", should the focus be on the first action or would it make sense to focus the last?

Good question: I did ask myself the same tbh.
IMO we could do with both, but the more intuitive would be to have it focus the last when coming from the right and the first when coming from the left.

I can create an issue to handle that, since this seems out of scope for this PR.

Agree @romgrk ?
