Removed LINQ and lambdas from initialization of thisFrameGOs variable. Performance tested on AWSIM/Scenes/Samples/LidarSkinnedStress scene since it provides a stable number of entities. The performance of the "Find changes and make TODO list" profiler section improved drastically from taking 21 ms to 9 ms on my machine:
Lenovo Legion Laptop
Processor: 1x 10th Generation Intel® Core™ i7-10750H Processor(Core™ i7-10750H)
Graphics: 1x NVIDIA®GeForce RTX™2070 SUPER™
I tried removing LINQ and lambdas from all other parts of SceneManager.cs, but this offered no noticeable performance improvements, so I decided to keep the old code for readability reasons.
