UEFI spec defined ACPI Tables at boot time can be contained in memory of
type EfiACPIReclaimMemory or EfiAcpiMemoryNVS, although InstallAcpiTable
with AcpiTableProtocol will only allocate memory with type
EfiACPIReclaimMemory (Except FACS).
This patch provides an optional method controlled by PCD to avoid using
EfiACPIReclaimMemory, by setting the PCD PcdNoACPIReclaimMemory to TRUE,
all ACPI allocated memory will use EfiAcpiMemoryNVS instead.
