Make CopyMem() and SetMem() be EFIAPI

For wildly unknown reasons, EFI Boot Services includes CopyMem() and
SetMem() functions, and they are marked as EFIAPI functions.

This patch marks gnu-efi's CopyMem() and SetMem() as EFIAPI functions,
and makes their exposed API match the misguided nonsense in the EFI
spec, so that they can be used there in a test environment.
