Make scripts capable of 32-bit Windows builds

Now binaries can be (cross-)built using GCC for 32- and 64-bit Windows.

Additional improvements:
 - Within MSYS2, try to install the required dependencies automatically.
 - Within MSYS2, fix passing libdir paths to pkg-config.
 - Prune documentation from extracted package files,
   addressing the incredible slowness of Windows filesystem operations.
 - Fix the script name in README.adoc instructions.

plus rsvg-convert from librsvg2, and icotool from icoutils.
Beware that the build will take up about a gigabyte of disk space.

$ sh -e msys2-configure.sh builddir
$ meson install -C builddir
If everything succeeds, you will find a portable build of the application
