test: add xpbd collider for chunk back. remesh only for neighbor comp…

…leted chunks

perf:

only render:
0dist = 140fps
20dist = 18fps, sky = 25fps 35fps
20dist in high air no visible chunk = 100fps

render+xpbd collider:
 0dist=140fps
20dist=17fps, sky = 24fps
20dist in high air no visible chunk = 60fps
