ConTeXt writer: unify link handling (#8096)

Autolinks, i.e. links with content that's the same as the linked URL,
are now marked with the `\url` command. All other links, both internal
and external, are created with the `\goto` command, leading to shorter,
slightly more idiomatic code. As before, autolinks can still be styled
via `\setupurl`, other links via `\setupinteraction`.
