I propose adding the property `media` to `AdminSite` class, with similar
functionality as `ModelAdmin.media`. The main reason for it is making it
easy to add any JS/CSS globally for every admin page, and it will make the
media management more consistent across the admin.

While it is possible to do that now by extending one of the base templates
and manually adding the script or link tag, the main benefit will be the
ability to separate this from the templates completely and in future,
maybe moving all hard-coded media html tags to `AdminSite.media` thus
making the template cleaner and making it possible to take advantage of
`Media` merging logic.

Instalation of packages that add custom styles or scripts would be
simplified, and be as easy as inheriting from a admin site mixin:

{{{#!python
class CustomAdminSite(PackageMixin, AdminSite)
...
}}}

Implementation would require adding the `AdminSite.media` property and
small modification to the `admin/base.html` template.

If this issue is accepted, I would be happy to take on it.
