Add some DISABLE_DYNLOADING ifdefs to osl/w32, as for unx

Lots of things will have to be tweaked to build core statically for
Windows. This is just one small isolated and fairly obvious trivial
commit. (Assuming that in the disable-dynloading case, for Windows we
want to drop the same dynamic library loading functions in osl as for
Unixish systems.)
