Add minetest.bulk_set_node call + optimize Environment::set_node call (#6958)

Browse source 
* Add minetest.bulk_set_node call + experimental mod unittest

* Optimize set_node function to prevent triple lookup on contentfeatures

Do only one lookup for old, and try to merge old and new lookup if node is same than previous node

* Add benchmark function + optimize vector population to have real results
