[IMP] web: add decoration support for all field widgets (#25160)

It is sometimes useful to be able to customize slightly the color of a
field depending on some conditions on the current record.

For example, imagine that we want to show a VAT number field in green/red, if
it was validated or not. To do that, we can add a field with an
onchange, and simply add decoration-danger and decoration-success
attributes to the field.
