Allow to add any field type to media

[mrleblanc101]

What if we want to add a Checkbox ?
We want to allow admin to add a watermark using our CDN.

Instead of:

->withCustomFields(
    ['copyright' => __('Copyright')],
    overwrite: false
)

Something like this ?

->withCustomFields([
        Text::make(__('Copyright'), 'copyright'),
        Checkbox::make(__('Watermark'), 'watermark'),
    ],
    overwrite: false
)

We'd also love to add Relationship with media. For exemple: Tagging people (from our people table, not just plain text) in an image.

->withCustomFields([
        Text::make(__('Copyright'), 'copyright'),
        Checkbox::make(__('Watermark'), 'watermark'),
        Tags::make(__('People'), 'people'),
    ],
    overwrite: false
)

A feature like this is implemented in https://github.com/ebess/advanced-nova-media-library#custom-properties
