wayland: Implement activate() API and use portals to open URLs and paths (#13336)

This PR consists of two main changes:
1. The first commit changes the `open` crate for opening URLs/paths for
the `OpenURI` desktop portal. This fixes the activation token not being
passed to programs (at least on KDE).
2. The second commit implements the window `activate()` API on Wayland.
This allows KWin and Mutter to show a visual indicator when the window
is requesting attention. (see
