MdeModulePkg/Library: PcdAcpiS3Enable set FALSE cause Assert

Some platforms don't support S3 with PcdAcpiS3Enable set as False.
Debug mode bios will ASSERT at this time as Follows.
ASSERT_RETURN_ERROR (Status = Out of Resources)
DXE_ASSERT!: Edk2\MdePkg\Library\BaseS3PciSegmentLib\S3PciSegmentLib.c
(61): !(((INTN)(RETURN_STATUS)(Status)) < 0)

Steps to reproduce the issue:
1.Set PcdAcpiS3Enable to FALSE.
2.Build the bios in debug mode.
3.Power on and Check the serial log.
Note: Prerequisite is that S3PciSegmentLib is Called and
the caller's code is run.

Root Cause:
S3PciSegmentLib call S3BootScriptLib controlled by PcdAcpiS3Enable.
If PcdAcpiS3Enable set as false, S3BootScriptLib will return error
status(Out of Resources).
S3PciSegmentLib will ASSERT if S3BootScriptLib return error.

Solution:
Make S3BootScriptLib return success if PcdAcpiS3Enable was disabled,
which behave as a null S3BootScriptLib instance which just return success
for no action is required to do.
