Fix missing types in storybook (OnyxSelect)

[BoppLi]

Task: try to get rid of "Omit" / "Pick", instead split up the types that are consumed. Example: OnyxSelectInputProps should be split so it can be used directly by OnyxSelect

dev storybook shows e.g. "readonly" not below "props" in OnyxSelect, is this a known issue? https://storybook.onyx.schwarz/?path=/story/components-select--readonly

and if you open another example, it's totally gone.. https://storybook.onyx.schwarz/?path=/story/components-select--multiselect

I found out that this is solved after removing "label" from OnyxSelectProps. It is already inherited from OnyxFormElementProps, so maybe because it was there twice, Storybook broke a bit?

=> do we still want to restructure the types?
