AARCH64 systems never require compatibility with legacy ACPI OSes, and may not have any 32-bit addressable system RAM. To support ACPI on these systems, we need to be able to relax the 4 GB allocation restriction. So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing which ACPI versions are targeted, and wire it up it up to the memory allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b is not among the supported versions, the memory allocations are not limited to 4 GB, and only table types that carry 64-bit addresses are emitted. Note that this will inhibit the publishing of any tables that carry only 32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.
