Restore rich Text creation speed
634b59f187c8697f03a606cbacb5f0a69650ea7c caused a significant
performance regression during layout of any Text item with RichText,
by calling QQuickTextDocumentWithImageResources::setPageSize() with an
accurate width in ensureDoc(); but ensureDoc() is called multiple
times, and doesn't need to calculate actual layout. The accurate
width is needed (at least) when doing layout of HTML tables that
contain percentage-based column widths. For that purpose it's enough
to set the correct "page" size in updateSize().
