x86/sev: Add SVSM vTPM probe/send_command functions
Add two new functions to probe and send commands to the SVSM vTPM. They
leverage the two calls defined by the AMD SVSM specification [1] for the vTPM
protocol: SVSM_VTPM_QUERY and SVSM_VTPM_CMD.
Expose snp_svsm_vtpm_send_command() to be used by a TPM driver.
