If HOB contains APCI table information, entry point of AcpiTableDxe.inf
should parse the APCI table from HOB, and install these tables.
We assume the whole ACPI table
(starting with EFI_ACPI_2_0_ROOT_SYSTEM_DESCRIPTION_POINTER)
is contained by a single gEfiAcpiTableGuid HOB.

If error happens when installing ACPI table, stop installing and removing
all the tables that are already added.
