This PR addresses feedback in #101467 (comment)

Couple of notes:

1. enum now only used to provide autocompletion suggestions and renamed accordingly.
2. Apparently errorMessage will be shown only from first item in anyOf
3. type: 'number' should be first otherwise number validation Value is above the maximum of 1000. won't be shown for numbers, however it can be moved lower to have same error message for 1001 and "10001"

Thank you!

@alexdima I've remembered why I haven't used clampedInt - font-weight: 10000 will be totally ignored by browser therefore my initial check was min <= val <= max to match browser behavior. Demo

I think it's better to match browser behavior and revert code back to min <= val <= max probably add explicit isNaN check if needed.

I agree that this is the behaviour of CSS, but these are editor settings, the behaviour of out-of-range values doesn't need to conform to the CSS specification. I think it is OK if we are consistent with our other settings, so we clamp small/large values. IIRC we do the same for fontSize and other editor settings.
