IntelSiliconPkg IntelVTdDxe: use gEfiAcpi10TableGuid for ACPI 1.0

According to definition (Acpi.h and MdePkg.dec),
gEfiAcpiTableGuid = gEfiAcpi20TableGuid, and the code is trying
to parse ACPI 2.0 first and then ACPI 1.0, but it uses
gEfiAcpiTableGuid wrongly for ACPI 1.0, this patch is to fix it.
