renderlist optimizations.

A few nice benchmarks here. i compiled my stuff with just scons and compared it to godot-4.4-stable. So, I'm sure it's probably even better if compiled right. For "Time", this patch got:

1000 Area 3d: 0.087 vs Godot's 0.13

Softbody 3d 500 Rigidbodies: Well, 0.97 vs Godot's 0.222

A few other "significant" ones, I only checked physics/rendering. It's a simple one so it shouldn't really create any issues for anything unless you just hate speed.

0.97 is more than 0.222 ...

[mcdubhghlas]

0.97 is more than 0.222 ...

Sorry. That was a typo, it should have been 0.097. But I double checked to verify, and I just hit 0.068 ms for it. Pic related:

This is the output in the terminal

And for additional clarification, this commit originally came from our other project, ReX Engine, and was cherry picked back to Redot. Hence the lighter than normal scrutiny, since it was already pretty thoroughly tested bench marked internally. Good catch on that though @Stand43 ! I totally should have caught that typo in the description.
