Force selecting haptic supported thread when creating HapticGenerator.

HapticGenerator is the haptic-generating effect, which will generate
haptic data based on audio data. As haptic data will be truncated on
non-haptic supported thread, HapticGenerator makes sense only on haptic
supported thread. In that case, force selecting haptic supported thread
when creating HapticGenerator. If there is no thread supporting haptics
channel, return a failure.
