general

There are a number of one-off implementations of routines for free'ing a string array scattered across libtopo - all of which are basically identical. This is a sign that this should be promoted to a module API. So this CR is to add such an interface and replace all the one-offs with it.

This change adds two new interfaces:

topo_mod_strfreev(topo_mod_t mod, char *strarr, uint_t nelem)

and

topo_hdl_strfreev(topo_hdl_t thp, char *strarr, uint_t nelem)

See the testing notes in the ticket: https://www.illumos.org/issues/11960
