Mitchell Horne 0d2224733e Implement GET_STACK_USAGE on remaining archs 
This definition enables callers to estimate remaining space on the
kstack, and take action on it. Notably, it enables optimizations in the
GEOM and netgraph subsystems to directly dispatch work items when there
is sufficient stack space, rather than queuing them for a worker thread.

Implement it for riscv, arm, and mips. Remove the #ifdefs, so it will
not go unimplemented elsewhere.
