This is a continuation of work started in #58948, handling all the cases of data from vector layers. No change of functionality, just changing what coordinates are stored in geometries sent to GPU.

Also:

• point and line symbol implementations internally use (x,y,z) coordinates instead of (x,z,-y) - QTransforms are used to flip the axes back to scene's coordinates
• instanced renderer's vertex shader has been cleaned up and made to work with QTransform
• extruded polygons textured rendering test was modified to use more appropriately scaled texture
• unused QgsTessellatedPolygonGeometry::setPolygons() was removed
