Star Zeng f53a313443 MdeModulePkg AcpiTableDxe: Don't uninstall Acpi Sdt Protocol at ReadyToLock 
1. The consumer of Acpi Sdt Protocol may want to use the API after ReadyToLock.
2. The ACPI system configuration table even could be overwritten,
   we see little issue in leaving Acpi Sdt Protocol installed.

Ard Biesheuvel f9bbb8d9c3 MdeModulePkg: AcpiTableDxe: make 4 GB table allocation limit optional 
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.
