Improve cacti and cane growth ABM (#4590)

- local functions, as they are not called by anywhere else
- delay water check of reed, first check height
- reduce number of get_node calls (for height 1,2,3 the old code used 4,5,4 calls, the new only 2,3,3)
- cane growth rate is also reduced

This will make the ABM cheaper.
