Fix Andreas' problem with checkboxes in legend + update SIP bindings

The problem was that rule-based renderer allowed cloned rules to have the same unique rule key.
That in turn created the confusion with checkboxes in legend. Now rules always have new rule key
when cloned. The only exception is when the whole renderer is cloned - in such case we preserve
their rule keys, so that other components (legend / visibility presets) can still keep using
the original rule keys.

Projects where this problem appears need to be fixed - the easiest way is to select all rules,
copy&paste them and remove the previous rules.

[BUGFIX] #11484 QGIS server: embedded layers are not published (GetCapabilities, GetMap, etc)

Issue #1072 QGIS server: embedded groups do not render in GetMap requests if
 leave layers are requested has been fixed 40d91457f6f069886c5ba1c28db1efb2ff4ccac7

But another fix about embedded layers lacks. A fixme annotation is in the
 QgsServerProjectParser::createLayerFromElement. This one is about return the
 layer if it is embedded.

In QgsServerProjectParser::createLayerFromElement, we need to generate a
 QgsServerProjectParser of the parent project to return the mapLayer for
 embedded layers. To do it, I use QgsCacheConfig to get the
 QgsServerProjectParser for the parent project.
