OvmfPkg: create a SEV secret area in the AmdSev memfd
SEV needs an area to place an injected secret where OVMF can find it
and pass it up as a ConfigurationTable. This patch implements the
area itself as an addition to the SEV enhanced reset vector table using
an additional guid (4c2eb361-7d9b-4cc3-8081-127c90d3d294).
