The uefi_call_wrapper exists to convert to the right calling convention and presumably predates compilers that can do so natively. The only architecture where this is even needed is x86_64. But because we are building with GNU_EFI_USE_MS_ABI defined, the EFIAPI macro tells the compiler to use the right calling convention for EFI functions. Our shim callback (which is called by EFI itself) already relies on this. This also adds a safety check to make se we are compiling with GNU_EFI_USE_MS_ABI defined and also adds it to the compiler args unconditionally. It is only used with x86_64 anyways, so it should be fine to do so. EFI_FUNCTION_WRAPPER is unused in gnu-efi, so it is dropped.
