efi/x86: Rename efi_is_native() to efi_is_mixed()

The ARM architecture does not permit combining 32-bit and 64-bit code
at the same privilege level, and so EFI mixed mode is strictly a x86
concept.

In preparation of turning the 32/64 bit distinction in shared stub
code to a native vs mixed one, refactor x86's current use of the
helper function efi_is_native() into efi_is_mixed().
