OvmfPkg/AmdSvsmLib: Add support for the SVSM create/delete vCPU calls
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654
The RMPADJUST instruction is used to alter the VMSA attribute of a page,
but the VMSA attribute can only be changed when running at VMPL0. When
an SVSM is present, use the SVSM_CORE_CREATE_VCPU and SVSM_CORE_DELTE_VCPU
calls to add or remove the VMSA attribute on a page instead of issuing
the RMPADJUST instruction directly.
Implement the AmdSvsmSnpVmsaRmpAdjust() API to perform the proper operation
to update the VMSA attribute.
