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.

+### Building and running gtktiledviewer on Windows
+
+A pre-requisite is pre-built GTK3 libraries. See [official GTK documentation](https://www.gtk.org/docs/installations/windows/).
+Building of gtktiledviewer on Windows is enabled by passing
+
+    --with-gtk3-build=<path/to/GTK3/build/directory>
+
+to configure.

+Running the compiled executable requires GTK's bin in PATH:
