SWDEV-142271 - Performance drop is observed in Ocean Surface Simulation of Compubenchcl in 17.50 when compared to 17.Q4.1
	- Rewrite the adaptive mode for waveliimiter. Make sure the performance feedback corresponds to the right wave count. Add the new sampling logic to find the best number, based on average performance.
