Enable gtktiledviewer on Windows

A new configure argument is introduced:

--with-gtk3-build=<absolute path to GTK3 build>

When provided, libreofficekit_selectionhandles package, libreofficekitgtk
library and gtktiledviewer executable would be built on Windows using the
GTK3 libraries in the passed directory, that must contain lib/pkgconfig
subdirectory with correct pkg-config data.
