Add FileUpload component

[zemirco]

I know you already have the ld-input component with type="file".

It would be nice to have a more advanced file upload component to further improve the UX.

Let's have a look at other component libraries.

Ant Design https://ant.design/components/upload

IBM Carbon https://carbondesignsystem.com/components/file-uploader/code/

Dell Design System https://vanilla.delldesignsystem.com/2.21.0/index.html?path=/docs/components-file-input--basic

Edison™ Design System https://edisondesignsystem.com/file-upload?tab=2

Segment Evergreen https://evergreen.segment.com/components/file-uploader

Shopify Polaris https://polaris.shopify.com/components/drop-zone#navigation

As you can see some of them provide

• image preview
• list of files with delete button
• drag and drop (I know many browser do that natively but most of our users do not know that). It would be nice to have visual hints
• upload progress

🤞🤞 Maybe you could realize this ✨✨
