MdePkg: Add new definitions for Management Mode.
In PI 1.5 version, system management mode name(SMM) has been changed to Management Mode(MM). It impacts the current code which still use SMM/Smram/SMI keywords. This patch add new definition which use MM/MmRam/MMI keywords to follow new spec definitions.

Provides the parent dispatch service for the USB MMI source generator.

This service registers a function (DispatchFunction) which will be called when the USB-

contains a unique handle which may be used later to unregister the function using UnRegister().
