OvmfPkg: Realize EfiMemoryAcceptProtocol in AmdSevDxe

Browse Source 
When a guest OS does not support unaccepted memory, the unaccepted
memory must be accepted before returning a memory map to the caller.

EfiMemoryAcceptProtocol is defined in MdePkg and is implemented /
Installed in AmdSevDxe for AMD SEV-SNP memory acceptance.
