This adds support for the new wl_pointer events available in v5. The wl_pointer.axis_source events can be ignored for the purposes here, the main reason they exist is so that the combination of axis_source=finger and axis_stop triggers kinetic scrolling. We don't need to care about the source, axis_stop is enough for us to tell us when we're scrolling. The wl_pointer.frame events group events together and is intended as a mechanism to coalesce events together. This for example allows us to now send a single GTK scroll event for a diagonal scroll. Previously, the two wl_pointer.axis events had to be handled separately. The wl_pointer.axis_discrete event sends mouse wheel clicks where appropriate, and is translated into up/down/left/right scroll events. https://bugzilla.gnome.org/show_bug.cgi?id=756729
