OvmfPkg/AmdSev: use GenericQemuLoadImageLib in AmdSev builds 

Newer kernels support efistub and therefore don't need all the legacy
stuff in X86QemuLoadImageLib, which are harder to secure.  Specifically
the verification of kernel/initrd/cmdline blobs will be added only to
the GenericQemuLoadImageLib implementation, so use that for SEV builds.
