formatter: load templates section like a map file

Since a map file has another level to select a template (spec -> mapfile
-> topic), this isn't exactly the same as how a map file works. But I believe
most users would expect the new behavior.

A literal template is stored as an unnamed template so that it will never
conflict with the templates defined in [templates] section.

32874:dddba6f3e59c

    A map file defines a stand-alone template environment. If a map file
    selected, all templates defined in the file will be loaded, and the
    template matching the given topic will be rendered. No aliases will be
    loaded from user config.
