Kconfig: clean up the efi configuration status

The EFI_LOADER and EFI config options are randomly scattered under lib/
making it cumbersome to navigate and enable options, unless you really
know what you are doing. On top of that the existing options are in
random order instead of a logical one.

So let's move things around a bit and move them under boot/. Present a
generic UEFI entry where people can select Capsules, Protocols,
Services,  and an option to compile U-Boot as an EFI for X86
