Vein ore: Fix bug caused by changing perlinmap Y size (#7371)

Browse source 
Because vein ore uses 3D noise (all the other ores use 2D noise) the
perlinmap Y size can be different in different mapchunks when close
to the ore Y limits.
Previously this caused bugs in the vein structure because changes in
perlinmap Y size did not recreate the noise objects.

Delete and recreate the noise objects with the new Y size if Y size
has changed.
