Group stress test examples (#4289)
# Objective - Several examples are useful for qualitative tests of Bevy's performance - By contrast, these are less useful for learning material: they are often relatively complex and have large amounts of setup and are performance optimized. ## Solution - Move bevymark, many_sprites and many_cubes into the new stress_tests example folder - Move contributors into the games folder: unlike the remaining examples in the 2d folder, it is not focused on demonstrating a clear feature.

## Stress Tests
|

These examples are used to test the performance and stability of various parts of the engine in an isolated way.

Due to the focus on performance it's recommended to run the stress tests in release mode:
|
||||
|
