MdeModulePkg: DxeCore: Correct Runtime Granularity Memory Type
Per the UEFI spec 2.10, section 2.3.6 (for the AARCH64 arch, other
architectures in section two confirm the same) the memory types that
need runtime page allocation granularity are EfiReservedMemoryType,
EfiACPIMemoryNVS, EfiRuntimeServicesCode, and EfiRuntimeServicesData.
However, legacy code was setting runtime page allocation granularity for
EfiACPIReclaimMemory and not EfiReservedMemoryType. This patch fixes
that error.
