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.
