ENH: make some vectorTensorTransform methods inplace

Browse Source 
- avoids intermediate allocation and re-assignment to self (#3374)

BUG: checkMesh (application) with questionable memory handling (#3374)

- move the contents of the new points instead of attempting to transfer
  the entire list

COMP: replace mapDistribute specializations with if constexpr handling

- simplify future maintenance
