input: don't map wheel events to BTN_{BACK,FORWARD}
BTN_BACK and BTN_FORWARD are separate buttons. The scroll wheel don't
have any button mappings in libinput/wayland, so make up our own
defines.
This allows us to map them in mouse bindings.
Also expose BTN_WHEEL_{LEFT,RIGHT}. These were already defined, and
used, internally, to handle wheel tilt events. With this, they can
also be used in mouse bindings.
Finally, fix encoding used for BTN_{BACK,FORWARD} when sending mouse
button events to the client application. Before this, they were mapped
to buttons 4/5. But, button 4/5 are for the scroll wheel, and as
mentioned above, BTN_{BACK,FORWARD} are not the same as scroll wheel
"buttons".
