meson: Document build targets, add 'help' target
Currently important build targets are somewhat hard to discover. This commit documents important meson build targets in the sgml documentation. But it's awkward to have to lookup build targets in the docs when hacking, so this also adds a 'help' target, printing out the same information. To avoid having to duplicate information in two places, generate both docbook and interactive docs from a single source.
