We need to stub the SVSM vTPM protocol in the UefiCpuPkg in order to
support a SEV-SNP guest running under a SVSM at VMPL1 or lower.

OvmfPkg/AmdSvsmLib: Add the SVSM vTPM protocol
As described in the SVSM specification, guest components can call to the
SVSM vTPM through the vTPM protocol (protocol-id 2).
The SVSM vTPM protocol follows the Microsoft TPM Simulator interface
(MSSIM) and supports two services:
- SVSM_VTPM_QUERY (call-id 0): query MSSIM commands and vTPM features
supported.
- SVSM_VTPM_CMD (call-id 1): send a MSSIM command to be run by the vTPM
and get the result.
This patch adds support for SVSM_VTPM_QUERY and SVSM_VTPM_CMD to invoke
a SVSM when the guest is running at VMPL0.

SecurityPkg/Tpm2DeviceLibDTpm: Add TPM2 lib supporting SVSM vTPM
SEV-SNP provides a feature known as VM Privilege Level (VMPL), which
allows for services to be run in the guest at different privilege
levels. By running at VMPL0 (most privileged VM level), the SVSM can be
used to provide privileged services, e.g. a virtual TPM, for the guest
rather than trust such services from the hypervisor.
This patch adds a DTpm driver to communicate with a virtual TPM running
in the SVSM. The driver follows the vTPM protocol documented in the SVSM
specification.
SVSM vTPM functionality is available as new device and instance
libraries, which can be consumed optionally, keeping changes to the
regular TPM implementation minimal.
