Session Management

[danirabbit]

Problem

It's handy for apps to be able to do things like inhibit the session from going to sleep as well as responding and ending tasks before the session goes to sleep

Proposal

Document the APIs related to interacting with the session state such as Gtk.Application.inhibit and responding to session state changes via LibPortal

Prior Art (Optional)

No response

Oh actually it looks like Gtk.Application.screensaver_active exists as well
