view: validate move/resize request from clients

Move/resize requests from xwayland views and xdg toplevels should be
ignored when the view is not pressed.

This is relevant for touchpad taps with <tapAndDrag> disabled.

When the user taps the client surface (e.g. chromium and mpv) with the
setting above, libinput sends button press & release signals so quickly
that the compositor receives move/resize request from the client AFTER
the button release signal is processed, so `interactive_finish()` is
never called.
