UefiPayloadPkg: Add a common SMM control Runtime DXE module

This module consumes SMM Registers HOB (SMI_GBL_EN and SMI_APM_EN) to
install SMM control 2 protocol gEfiSmmControl2ProtocolGuid.
The protocol activate() would set SMI_GBL_EN and SMI_APM_EN and trigger
SMI by writing to IO port 0xB3 and 0xB2.
