LibGUI: Make `propagate_shortcuts` handle different level of propagation

First, this patch renames the function
`propagate_shortcuts_up_to_application` to `propagate_shortcuts`.
Handling those levels, will allow us to differentiate shortcuts at
`Window` level and `Application` level. Which will be convenient to
handle dialog-specific shortcuts.
