ARM Packages: Force the SEC modules to be 2K aligned for AArch64
The AArch64 Vector Table must be aligned on a 2K boundary. The FDF specification does not support 2K alignment but support 4K. A clear comment has been added to help integrator to understand why the assertion fails when porting to a new AArch64 platform.
