The current module checks the value of gEfiAcpiVariableGuid hobs and could assert if there is no such hob available. However, these hobs are only available if a platform elects to support S3. Thus this change moves the hob copy logic behind a PCD check to prevent unnecessary asserts. Signed-off-by: Kun Qin <kuqin12@gmail.com>

The current module checks the return status of MmIplDispatchMmDrivers. Any failure would cause the system to assert. However, this should not be deemed as fatal since the result could be entirely implementation defined on the Standalone MM core side. This change loosens the check and not to do asserts on dispatcher requests. Signed-off-by: Kun Qin <kuqin12@gmail.com>

Description
Current implementation of the
StandaloneMmIplPeihas a few design differences compared to MM supervisor.This will introduce more maintenance burden as we move to the next phase of MM supervisor.
This change is made to try to converge the 2 designs, at least from the perspective of IPL, in order to use the IPL as is and still conform to the MM supervisor modelity.
For details on how to complete these options and their meaning refer to CONTRIBUTING.md.
How This Was Tested
This is tested on QEMU Q35 and booted to UEFI shell.
