audio: play DualSense haptics from vibration audio ports (#843)

* audio: play DualSense haptics from vibration audio ports

Games drive the DualSense's actuators through a vibration audio port, one channel per actuator.
These ports had no device, so their samples were dropped. Over USB the DualSense is a 4-channel
audio device whose back channels feed the actuators; play the port's samples there through SDL.

The device is looked up while the port plays, so the controller can be connected at any time. The
queue keeps about the latency of the regular audio path, with the playback rate nudged by up to 3%
when the port is fed off real time.

While haptic audio plays, hold a DualSense's rumble at zero: SDL disables audio haptics whenever
rumble is non-zero.

Add pad_haptics tests for the sample conversion, device-name matching and rate correction.

* Simplify DualSense audio haptics and restore idle rumble
