Description

In Formio.js 4.x, we have the ability to skip mask validation by checking the skipMaskValidation property in the instance. To maintain backward compatibility, we have retained this instance check. This PR introduces the ability to skip mask validation by adding the skipMaskValidation flag to the validate object in the JSON configuration.

This is something of a nit, but wouldn't the check for skipMaskValidation just be better inside of the isValidatableComponent fn?

[brendanbond]

e.g. the component is not validatable if it has skipMaskValidation

I refactored the isValidatableComponent function to improve readability. The previous implementation with two additional conditions made the function difficult to understand at first look. Is it fine?
