view source: add content_type metadata (#13859)

Browse Source 
# Description
Add content type metadata to the output of `view source`.

I've gone along with the mime type used [here][xdg], but this shouldn't
be merged until there is consensus #13858.

`to nuon`'s output has content type `application/x-nuon`

[xdg]:
https://gitlab.freedesktop.org/xdg/shared-mime-info/-/merge_requests/231

# User-Facing Changes
Combined with `metadata access`, allows richer display_output hooks.
Might be useful with other commands that make use of content_type like
the `http` commands.
