Hyundai: match ego speed on dash (#25235)

* hyundai: match speed on dash

* still needs conversion to m/s

* always use CF_Clu_VehicleSpeed2

* clean up, like honda

* experiment

* to the source

* works pretty well on optima (matches exactly on Sonata)

* could be 0.5

* clean up test

* revert test_moedls

revert test_moedls

* woops

* woops.

* .

* fix hyst

* only CF_Clu_VehicleSpeed

* omgomgomg

* add all this mess because it always takes a while

* set vEgoCluster

* fix all rounding errors

* stash

* clean up

* clean up

* fix metric conversion

* only calculate when updated

* try to filter (didn't look great from plots)

* Revert "try to filter (didn't look great from plots)"

This reverts commit 7e9876c237.

* clean up

* update refs
