add input file components

This PR

Adds the InputFile component, which supports a dropzone, a button and an icon button. It has a variety of features, such as:

• you can specify replaceOnUpload which decides if the uploaded files should be replaced or extended if you upload again
• you can specify showFiles if files should be shown or not. for dropzone, if this is enabled (which it is by default), the user will have the ability to remove items as well.
• quantity: one or multiple files?
• ... and more

Notes

• No notes to add

Fulfilled the scope of this repo?

• The same functionality of the component can not be achieved with theming, basic styling or composition of existing components
• The component implements an element of the DHI Design Guidelines or is otherwise generic enough in functionality and close enough to the DHI CVI that it is likely to find reuse in other projects
