wayland: Don't send proximity_in for new resources

Browse Source 
Mutter sends a proximity-in event before the required tablet tool
resource is properly allocated on the client. This is violating the
Wayland protocol. Because libwayland ignores events for objects it
doesn't know yet, this is not noticeable in most applications. However,
if https://gitlab.freedesktop.org/wayland/wayland/-/issues/176 gets
fixed, these applications would likely crash immediately. Therefore this
PR removes the responsible code which, again, shouldn't have any effect
on client applications as they ignore this event anyway.

Relevant part of the spec:

    This event can be received when the tool has moved from one surface to
    another, or when the tool has come back into proximity above the
    surface.
