InputNumber: add leading and trailing slots

Package

v4.x

Description

The InputNumber allows format-options via Intl.NumberFormat(), which works fine for standardized units. Hover, if we need to append a custom value (e.g a unit like px) this can't be done through formatting. Therefore it'd be useful to provide leading and trailing slots like in other components, or alternatively add an prefix / suffix prop.
