[code-cleanup] Cleanup and minor optimisation of the Questions components params interchange

[veronikaslc]

Code refactoring/optimisation changes:

• answerNodeType and isMultivalued are now calculated inside of the Answer component
• removed explicit properties that duplicate the properties from the questionDefinition, now they are transfered to all Question components as part of the questionDefinition as it should be

Code cleanup changes:

• removed unused imports
• removed unused props
• bundled props passed to Answer with {...rest}
• cleaned up comments
• removed text: PropTypes.string, from props passed to question components
