win32: Make the static build work with MinGW when posix  threads are used

MinGW does not support the use of DllMain() for static builds, but that
is currently always used on Windows, partly because it is needed for
handling win32 threads and because there are problems with MSVC
optimizing constructors away (see 7a29771a743a8b5337).

To make the static build at least work in case mingw+posix threads are used,
switch to using constructors for that. The g_clock_win32_init() call is
moved into glib_init(), so it's also called in that case.

If mingw+static+win32 threads are used abort the build early and print
an error message.

----

A similar patch is currently used in msys2 [0], but the one here limits the change to mingw + static + posix threads.
