Restore some windows-tdep.c code

When I removed init_w32_command_list, I weirdly neglected to see if it
was called anywhere else.  This patch restores the function, which is
called from windows-nat.c.  Sorry about the breakage.

Is it possible to have a windows-native gdb that isn't also using
windows-tdep?

Anyway, I'm checking this in.
