Robin Gareus 5c4a2025f1 Fix touching mute automation (mostly)
controllable->set_value() from GUI context will eventually queue
a session-rt command. By the time the realtime command runs, the
controllable needs to be in "touch" mode.

The AutomationController "toggle" UI worked around this by directly using
the underlying API (ignoring slaved-controls and ignoring groups).
The RouteUI's GUI wasn't able to write mute-automation at all.

This commit is a compromise: press + hold (touch) + release button.

(it may need further special-casing for _desc.toggled in
AutomationControl::actually_set_value(), also undoing automation-writes
is currently  not working correctly)
