bootctl implements three types of operation: those that work with an EFI boot loader, those which work with any EFI boot loader that implements the boot loader spec + interface, and finally those specific to sd-boot. Previously the --help text and the man page mixed them all up. Let's put them clearly in three separate sections however, to communicate clearly what is supposed to work everywhere, and what is specific to systemd-boot or boot loaders implementing the two specs. This adjusts wording here and there, but is mostly just about re-ordering existing docs, and putting them under new sections.
