bootstd: Add an implementation of EFI boot
Add a bootmeth driver which handles EFI boot, using EFI_LOADER.
In effect, this provides the same functionality as the 'bootefi' command
and shares the same code. But the interface into it is via a bootmeth,
so it does not require any special scripts, etc.
For now this requires the 'bootefi' command be enabled. Future work may
tidy this up so that it can be used without CONFIG_CMDLINE being enabled.
There was much discussion about whether this is needed, but it seems
that it is, at least for now.
