Title: [FIXED] #11572 ilter Legend By Map Content doesn't maintain point displa...

...cement legend

For point vector layer render with 'displacement point', when 'Filter
Legend By Map Content' is activated, the legend is not rendered even
if it has to be.

It's due to QgsPointDisplacementRenderer that embedded the real
renderer.

The solution proposed in this patch is to get the embedded renderer
for QgsPointDisplacementRenderer.
