ArmPkg,ArmPlatformPkg: Allow dynamic PCDs for memory base and size
This changes the definition and a bunch of references to gArmTokenSpaceGuid.PcdSystemMemoryBase and gArmTokenSpaceGuid.PcdSystemMemorySize so they can be declared as dynamic PCDs by the platform. Also, move the non-SEC call to ArmPlatformInitializeSystemMemory() earlier, so a platform has a chance to set these PCDs before they are first referenced. The purpose is allowing dynamically instantiated virtual machines to declare the system memory by passing a device tree.
