feat(pointpainting_fusion): enable cloud display on image

[vividf]

Description

The PointPainting fusion node disables plotting the point cloud on the image because it uses push_back within an OpenMP parallel loop.

#if 0
// Parallelizing loop don't support push_back
if (debugger_) {
debug_image_points.push_back(projected_point);
}
#endif

This PR introduces a method to store the projected points in local vectors and merge them after the for-loop. These updates make it easier for developers and users to debug.
