xwayland: assume no WM_HINTS means window wants input

Browse Source 
Some X11 clients (e.g. Chromium, sxiv) don't set WM_HINTS. The spec
says:

> Window managers are free to assume convenient values for all fields of the
> WM_HINTS property if a window is mapped without one.

Our wlr_xwayland_icccm_input_model function assumes missing WM_HINTS
means the window doesn't want input, but this is incorrect. Assume the
window wants input unless it explicitly opts-out by setting WM_HINTS.
