Default to disabling ImageMagick (Bug#33587)
ImageMagick has continuing stability and security problems, suggesting
that 'configure' should disable it by default. See Glenn Morris's notes
at: https://lists.gnu.org/r/emacs-devel/2018-12/msg00036.html
* INSTALL, etc/NEWS, nt/INSTALL.W64: Mention this.
* configure.ac (imagemagick): Default to off.
