Provide support for "masks" in InputField component

[ghost]

As a common use case, an InputField should only allow some well defined patterns, like only numbers in a specific format like money amounts or credit card numbers and so on. This is where so called "masks" come into play.

As a really neat feature we should try to find some good support for such uses cases on the "headless" level API of InputField component.

We should have a look at https://imask.js.org/

Key questions to solve:

• abstraction over the possibilities of the underlying JS lib or better expose its API?
• make its usage optional!
