[api-minor] Add basic support for Launch actions (issue 1778, issue 3897, issue 6616)

[Snuffleupagus]

In general we neither want, nor can, support arbitrary Launch actions. But in practice, all the cases we've seen so far just contains relative URLs to other PDF files. Building on PR #7689, we can thus at least support basic Launch actions.

Fixes #1778.
Fixes #6616.
(Also fixes one of the points in #3897.)

Thank you! I agree that this is probably the most we can do for Launch actions.
