Introducing the MSDLPlayer in Launcher via a wrapper singleton.

The player is the main API to the MSDL library (also used in SysUI) that
implements the Multi-sensory Design Language in the system UI. This CL
also includes an example of the API usage, when the user swipes up to
reveal AllApps, or taps on QSB.

Test: manual. Verified that the MSDL haptics play when swiping to reveal
  AllApps and tapping on QSB.
