feat: implement deeper throttling for Transform, MeshRenderer and GltfContainer

[leanmendoza]

What?

• take a deep throttling measuring the end_time_us each 10 transform update and each 1 mesh_rendere/gltf_container update
• move add_child from main_tree queue (gltf_container.gd) to scene processing stage

Why?

Avoid processing time that is longer than the stipulated

Code looks great! Tested and it's working.

Maybe, and just maybe, and if you want, we can separate in another PR the Transform, and iterate a bit over it to make look better. Right now the scene transform updates for neighborhood scenes are laggy.

But are we going to use this code? Can we change to a TODO: discard current_dirty for Transform that is no longer used
