Freshly deleted objects are temporarily "inert" until their destruction
is acknowledged by the compositor.
Inert objects are ignored. By doing so, we mistakenly returned too
early and missed some FD cleanup logic. This patch ensures that any
outstanding FDs are always closed by moving its logic outside of the
message handling routine.

`send_wayland_message` takes in the number of words, not its byte size.
This meant that we were sending quite a bit of out-of-bounds stuff
alongside the four arguments required by
`xdg_positioner::set_anchor_rect`, which triggered an assertion on Jay.
This didn't pop up before because the C wayland server library does not
seem to check this, but it's a valid (and useful!) assertion
for other server implementations nonetheless.
This patch switches to the initializer_list syntax to make the intent
clearer.
This patch introduces a new protocol proxy, which multiplxes Wayland
clients into a single connection, allowing us to redirect calls (e.g.
create toplevel -> create subsurface). Mixed with some state tracking
and emulation, we can embed a full-featured client into the editor.
