compositor,shell: move debug key code to core
The code for the key binding that triggers debug key bindings, that is,
the code that makes mod+SHIFT+SPACE work, used to live in shell.c. I
want to make the debug key bindings available in ivi-shell too, so this
code should be shared. Move it to core.
The code was originally introduced in
commit c509d2b152
so update the copyright in binding.c to reflect that.
