oliverpool 83ea43cf49 frontend: generic lazy loader for webcomponents (#8510)
After seeing #8111 use a webcomponent, I think that they are a neat usecase for Forgejo where most of the frontend is backend-generated, with some "island of enhancements".

I am considering using a webcomponent for the CITATION management (last occurrence of [`Blob.GetBlobContent`](https://codeberg.org/forgejo/forgejo/issues/8222)), however I noticed that the developer experience wasn't ideal.

With this PR it would be very easy to declare a webcomponent, which will be loaded only if needed (I converted `model-viewer` and `pdf-object` to this technique).

Some cleanup in the neighbor webcomponents.

## Testing

1) Create a new repository or use an existing one.
2) Upload a `.pdf` or `.glb`  file (such as https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/testdata/data/viewer/Unicode%E2%9D%A4%E2%99%BBTest.glb)
3) Open the Network inspector and view the file in the repository.
    - After a short loading spinner, the PDF or 3D model should be rendered in a viewer
    - the related JS should have been loaded (e.g. http://localhost:3000/assets/js/model-viewer.494bf0cd.js)
    - visiting another page and check that this JS file isn't loaded
