Add a "load globally" option

Problem/Motivation

Typically this is a library module that doesn't load Vue without being set as dependency in another module.

For contrib cases, where Vue is used on all pages, we could add a "Load globally" option that loads the library on all pages for convenience and non-developers. Still I think this is a super-edge case.

Code-wise you could look into the Photoswipe module for example, how to do that, if anyone is interested to provide a MR.
