[backend-integration] processing assets not directly used by Vite

[lubomirblazekcz]

Clear and concise description of the problem

If static assets are referenced in templates on backend (.twig, .blade, .latte, etc.), Vite will not process them and they are not included in manifest file.

A way how to get around that is described here #2375 (comment)

Suggested solution

rollupOptions.input should accept any kind of file type, including png, jpg, svg, etc and treat them as assets. This is not currently possible and are generated as empty chunks.

Generated an empty chunk: "fragment.svg"
Generated an empty chunk: "icon.png"

What about introducing option like build.assetsInput as string[] with glob paths?

And each glob could then include assets viaimport.meta.glob('/path/to/assets/**') perhaps? This way they could be added to build as described in #2375 (comment)

Oh, I had a similar problem when I pack a mpa.

I use <img src="@images/picture.jpg" alt="" /> directly in a html and I also put the picture into rollupOptions.input, but it became an empty js after build, and there's a info like this:

Generated an empty chunk: "images\picture".
