MdePkg: The prototype definition of EdkiiMemoryAcceptProtocol
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937
EdkiiMemoryAcceptProtocol is defined in MdePkg, the method AcceptMemory()
can be called when memory needs to be accepted.
EdkiiMemoryAcceptProtocol can be installed by architecture-specific
drivers such as TdxDxe. This allows different isolation architectures
to realize their own low-level methods to accept memory.
