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. Signed-off-by: Etienne Carriere <etienne.carriere@linaro.org> Reviewed-by: Ard Biesheuvel <ardb@kernel.org>
