REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1266af5e952159 abstracted generic functions
from different modules (IntelVTdDxe, S3SaveStateDxe, PcRtc,
DpDynamicCommand and PiSmmCpuDxeSmm). Some of them (IntelVTdDxe and
PcRtc) checked Table against NULL before accessing Table->Signature,
some (S3SaveStateDxe, DpDynamicCommand and PiSmmCpuDxeSmm did not.
The ScanTableInSDT() in Acpi.c of UefiLib was mainly from
S3SaveStateDxe, so it does not check Table against NULL before
accessing Table->Signature.
This patch updates ScanTableInSDT() to check Table against NULL first
before accessing Table->Signature.

Request to add a library function for GetAcpiTable() in order
to get ACPI table using signature as input.
After evaluation, we found there are many duplicated code to
find ACPI table by signature in different modules.
This patch adds new EfiLocateXXXAcpiTable() APIs in UefiLib
for the request and also the following patch to remove the
duplicated code.
