man: Add weston-bindings(7) describing desktop shell shortcuts

The desktop-shell-specific bindings were identified from
shell_add_bindings in desktop-shell/shell.c. Various general shortcuts
(like Ctrl+Alt+F) are provided by files in libweston/ and compositor/ .

Also introduce references to the new manual in weston(1) and weston.ini(5).

+The combination \fBmod + Shift + Space\fR begins a debug binding. Debug
+bindings are completed by pressing an additional key. For example, pressing
+T next may toggle timeline recording, and F may toggle texture mesh
+wireframes with the GL renderer. (In fact, most debug effects can be
+disabled again by repeating the command.) Debug bindings are often tied to
+specific backends.
