[PATCH v3 10/16] qapi/docs: remove implicit Plain section

[John Snow <jsnow@redhat.com>]

Prior to this patch, we always create an empty Plain section. Removing
this allows us to gradually phase out the "Plain" section in favor of
"Intro" and "Details" sections while keeping "Plain" around for the
interim churn during the series - meaning that we don't actually know
at __init__ time which type of section we'll have first.
