OvmfPkg: S3 Suspend: save ACPI context
"OvmfPkg/AcpiS3SaveDxe/AcpiS3SaveDxe.inf" (originally: "IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe/AcpiS3SaveDxe.inf") produces the EFI_ACPI_S3_SAVE_PROTOCOL. When found, this protocol is automatically invoked by BdsLibBootViaBootOption(), in file "IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c", right before booting a boot option, to save ACPI S3 context. At that point during BDS, our AcpiPlatformDxe driver will have installed the FACS table (which AcpiS3SaveDxe has a use-time dependency upon). With regard to dependencies: AcpiS3SaveDxe implements EFI_ACPI_S3_SAVE_PROTOCOL by relying on LockBoxLib.
