ArmPkg/Include: Add SVC function IDs for Management Mode.
SVCs are in the range 0xC4000060 - 0xC400007f.
The functions available to the secure MM partition:
1. Signal completion of MM event handling.
2. Set/Get memory attributes for a memory region at runtime.
3. Get version number of secure partition manager.
Also, it defines memory attributes required for set/get operations.
