clientobject, clouds, collision, clientsimpleobject: code modernization (#6260)

Browse Source 
* clientobject, clouds, collision, clientsimpleobject: code modernization

* use range-based for loops
* simplify some tests
* various code style fixes
* use emplace_back instead of push_back when necessary
* use auto on some iterators
* use default operator when needed
* unroll v3s16 creation on collisionMoveSimple
