gtkwidget: Do not check event sequence state before cancelling gesture

The sequence should be cancelled from the gesture despite its current state.
Also, there was a piece of pointer emulation that was not dropped here,
maybe breaking things further for the pointer emulated touchpoint.

Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4387
