efi/libstub: Extend native protocol definitions with mixed_mode aliases
In preparation of moving to a native vs. mixed mode split rather than a 32 vs. 64 bit split when it comes to invoking EFI firmware services, update all the native protocol definitions and redefine them as unions containing an anonymous struct for the native view and a struct called 'mixed_mode' describing the 32-bit view of the protocol when called from 64-bit code. While at it, flesh out some PCI I/O member definitions that we will be needing shortly.
