    build: let's now build the Windows installer with meson.
    
    The meson build still has a bunch of issues and build bugs compared to
    the autotools build, nevertheless the last blocker issue was dealt with
    a few days ago (PDB source generation).
    
    Moreover since the meson build on Windows especially makes such dramatic
    difference, in terms of build speed, this is a big improvement for
    Windows contributor's comfort, and as such is one less barrier of entry.
    Anyway I believe that most Windows developers build GIMP with meson now
    so sticking on autotools on this platform is just counter-productive.
    
    This is why it was decided to now make meson the recommended build
    system on Windows, as a further step toward a move to meson. It is still
    not the recommended build system on the other platforms yet.
