enh(NcSelect): Add visible input label

[Pytal]

Summary

• For [BITV] 9.4.1.2/6.2 - All autocomplete combobox elements in the "Profile visibility" section have not been properly implemented with the ARIA, making them not truly accessible for screen reader users. (1) nextcloud/server#41902
• Adds built-in visible input label which should be preferred over non-visible ariaLabelCombobox

Overall, fantastic PR. Just would recommend squashing the first, third, and fourth PR's together because they are to do with the actual template, and leave the second commit as it, because its to do with doc descriptions : )

heres a link on how to squash the commits even if they are not in order - dunno if you need this but I personally did not know you could squash out of order commits. Once that's done, this PR is good!

I'd like to keep the current logical separation of commits, will be a merge commit anyways :)

If I understand all correctly, with a new prop, we have two props that have a meaning of the component label:

1. inputLabel - visible label
2. ariaLabelCombobox - invisible label

And to avoid a11y issues:

• They should never have different value
• At least one should be present (or the label is outside and inputId is present)

I think we should either add a validation here to check both conditions, or we should mark ariaLabelCombobox deprecated and do the same what we have with Nc*Field to mark if label should be visible, or not, or it is outside.

[Pytal]

Warnings added without the deprecation as I think we should still allow setting ariaLabelCombobox, but todos have been added for the next major @ShGKme

Should we not use the same design as for the input boxes, text area ...?

Maybe what @susnux said is best, but for now, this LGTM

Can be done separately 💅
