rS331760: Make vm_map_max/min/pmap KBI stable.

Summary

There are out of tree consumers of vm_map_min() and vm_map_max(), and I believe there are consumers of vm_map_pmap(), although the later is arguably less in the need of KBI-stable interface. For the consumers benefit, make modules using this KPI not depended on the struct vm_map layout.

sys/vm/vm_map.c
4322	Shouldn't these routines just call the corresponding inline function?

sys/vm/vm_map.c
4322	I considered it and my feel was that it would only add an additional layer of obfuscation. I belive we did not make vm_page_*_KBI functions calling non-KBI variants for the same reason.
