BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654 Add initial support for the new AmdSvsmLib library to OvmfPkg. The initial implementation fully implements the library interfaces. The SVSM presence check, AmdSvsmIsSvsmPresent(), determines the presence of an SVSM by checking if an SVSM has been advertised in the SEV-SNP Secrets Page. The VMPL API, AmdSvsmSnpGetVmpl(), returns the VMPL level at which OVMF is currently running. The CAA API, AmdSvsmSnpGetCaa(), returns the Calling Area Address when an SVSM is present, 0 otherwise. The PVALIDATE API, AmdSvsmSnpPvalidate(), copies the PVALIDATE logic from the BaseMemEncryptSevLib library for the initial implementation. The BaseMemEncryptSevLib library will be changed to use this new API so that the decision as to whether the SVSM is needed to perform the operation can be isolated to this library. The VMSA API, AmdSvsmSnpVmsaRmpAdjust(), copies the RMPUPDATE logic from the MpInitLib library for the initial implementation. The MpInitLib library will be changed to use this new API so that the decision as to whether the SVSM is needed to perform the operation can be isolated to this library.
