Add a boolean parameter to the signal to inform the handler whether the
timeout completed successfully or not. This allows the shell to
gracefully end the pie timer animation and show a success animation when
the click happens.

Restarting the dwell click immediately would result in a contant
animation showing.
Start dwell detection in its own timeout handler, which has the nice
effect of not constantly showing a dwell animation and also making sure
that the dwell click timeout is started when pointer movement stops.

Sometimes the dwell timeout doesn't start again after quickly moving the
pointer. That happens if `should_stop_dwell` returns TRUE for the last
motion event we receive: It will stop the current timeout, but not start
a new one until we receive another event where the moved distance is
smaller than the threshold.
To fix this, always call `should_start_dwell` and `start_dwell_timeout`
instead of using an else-block, this makes sure we start a new dwell
timeout still during the same motion event that stopped the old one.

Add support for click assist, namely simulated secondary click (on a
long primary button press) and hover click support (simulate a click when
the pointer remains static for some time).
