Always notify seat on button press

When the cursor is not over a view, wlr_seat_pointer_notify_button is
not called. However, this function does the bookkeeping of the pointer
state with regards to the number of pressed buttons. Because this
function also sends updates to the focused view, it has been moved
down, after the focus has been updated.
