efi/libstub: Fix mixed mode boot issue after macro refactor
Commit
22090f84bc3f ("efi/libstub: unify EFI call wrappers for non-x86")
refactored the macros that are used to provide wrappers for mixed-mode
calls on x86, allowing us to boot a 64-bit kernel on 32-bit firmware.
Unfortunately, this broke mixed mode boot due to the fact that
efi_is_native() is not a macro on x86.
All of these macros should go together, so rather than testing each one
to see if it is defined, condition the generic macro definitions on a
new ARCH_HAS_EFISTUB_WRAPPERS, and remove the wrapper definitions on x86
as well if CONFIG_EFI_MIXED is not enabled.
