[PATCH 07/29] qapi/block-core.json: Use literal block for ascii art

[Peter Maydell]

The ascii-art graph in the BlockLatencyHistogramInfo
documentation doesn't render correctly in either the HTML
or the manpage output, because in both cases the whitespace
is collapsed.

Use the '|' format that emits a literal 'example' block
so the graph is displayed correctly.
