Fix SuperSlippery And StepTriggers persisting when UpdateSlip is call…

…ed (#34525)

* Fix superSlippery and stepTrigger values persist

- made values in SpillTileReaction's public so we can query the
prototype

- made the default values for slippery component and
StepTriggerComponent based on default constants
for easier resetting

- added a calculation and check in UpdateSlips to check
if a super slip is present as well as Update
relevant steptrigger and slip values based on the contents of the
solution

* The worlds biggest change
