Change of plan on this one. The current supervisor will not be made to work with this IPL. Instead, we will make the next gen support this naturally.

The other change for hob creation needs to get through.
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>
As the Hob data is a loosely contracted way of sharing data, using hobs to share communication buffer needs extra steps to ensure the intended buffer end up being used. This change will check to see if a pre-existing buffer is already created and skip the current coutine if available. Signed-off-by: Kun Qin <kun.qin@microsoft.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.
