manu | Add reloc keyworkd to let EFI bootstrap load amd64 kernel at any address
EFI bootstrap assumes it can copy the amd64 kernel to its ELF load address (that is KERNTEXTOFF - KERNBASE = 0x200000), but it can clash with previous UEFI memory allocation, as described here: http://mail-index.netbsd.org/tech-kern/2023/04/07/msg028833.html
This change adds a reloc keyword for controling where the EFI boostrap will copy the kernel image. Possible values are: default - the default and prior behavior, copy at 0x200000. none - do not copy and use the kernel image where it was loaded. address - specify an explicit address where to copy the kernel.
This comes with an amd64 kernel patch that makes it self-relocatable. It first discover where it was loaded in memory, and if this is different than the expected 0x200000, hhe the kernel relocates itself and start over at the right address.

It's possible that the old stack is overwritten by the kernel.

Merge x86 boot options in x86/boot(8) and add undocumented UEFI options
We were supposed to keep the option list in x86/boot(8), x86/dosoot(8) and x86/pxeboot(8) in sync, but it did not happen, hence it may work better with all the options in x86/boot(8). Also add the undocumented UEFI boot options.
Add a SELFRELOC kernel option for the sake of documentation clarity. Instead of telling that x86/boot(8) reloc command needs a kernel able to self relocate, we can tell it needs a kernel built with the SELFRELOC option. This keeps the reader from wondering what could make a kernel able to self relocate.
