fix/improvement(Chips) - Input as option

[gselderslaghs]

Proposed changes

Enhancement proposal as described in #527

• Allow building up the chips container without constructing the input field, as result the grid styling would always be applied
• Implement the rendering of the input element as option within the Chips component

Todo:

• Update documentation since Chips component is not necessarily a subcomponent within forms, but should be available as standalone component or as a form component if this enhancement get's approved

• Bug fix (non-breaking change which fixes an issue).
• New feature (non-breaking change which adds functionality).
