Optimization: CharacterMovementComponent doesn't need overlap check for combining moves for stationary characters

The overlap checks are used to see if we can warp back to the previous position to combine network moves to longer moves, but making sure we wouldn't put the character in penetration when rolling back in location. This is not necessary if the location is the same and other conditions are met (perhaps rotation is also the same, in case of overridden behavior in some licensees).

Have a networked character stand still in a game of at least 60fps so that move combining is active and used.

Observe overlap checks are running when standing still ("stat collision").
