Dice Demo: Add sound effects and shake to roll

Added the features in line with the spike outcome.
In addition, I modified the spawnDice function to
estimate if all dice are at rest before enabling spawning.
This prevents duplicate shake events and double tap
fumbles.

Task-number: QTBUG-116491
Pick-to: 6.6
Change-Id: Ia0dc59e469e008da5fc3afe2a7342381eadc1008
