[gimp/nieldg/remove-keyboard-grab: 575/575] app/display: Remove keyboard grab

    app/display: Remove keyboard grab
    
    Remove `gimp_display_shell_keyboard_grab()` and ...ungrab(), as there
    doesn't seem to be any good reason to grab the keyboard away from the
    compositor. More annoyingly, in some systems it will pop up a dialog
    on each first click whether the user is okay with inhibiting shortcuts.
