xwayland/selection: rename Wayland-facing data and helpers

Previously, wlr_xwm_selection_transfer.source_fd meant:

- the source of data in a Wayland -> X11 copy (good)
- the destination of data in a X11 -> Wayland copy (confusing)

This made reading through xwayland/selection/incoming.c difficult: in
many places, "source" actually means "destination".
