StandaloneMmPkg: build for 32bit arm machines

This change allows to build StandaloneMmPkg components for 32bit Arm
StandaloneMm firmware.

This change mainly moves AArch64/ source files to Arm/ side directory
for several components:  StandaloneMmCpu, StandaloneMmCoreEntryPoint
and StandaloneMmMemLib. The source file is built for both 32b and 64b
Arm targets.
