tests/qapi-schema: Add test of the rST QAPI doc-comment outputn
Add a test of the rST output from the QAPI doc-comment generator,
similar to what we currently have that tests the Texinfo output.
This is a bit more awkward with Sphinx, because the generated
output is not 100% under our control the way the QAPI-to-Texinfo
generator was. However, in practice Sphinx's plaintext output
generation has been identical between at least Sphinx 1.6 and
3.0, so we use that. (The HTML output has had changes across
versions). We use an exact-match comparison check, with the
understanding that perhaps changes in a future Sphinx version
might require us to implement something more clever to cope
with variation in the output.
