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.
