  Gdk, Gsk, Gtk: Regenerate docs.xml and .defs files

  using gtk files from gtk 4.20.1.
  The .defs files are identical to the ones in gtkmm 4.19.1,
  using gtk files from gtk 4.19.4.
  Remove documentation of enumerators in gdk_docs_override.xml and
  gtk_docs_override.xml. They are now included in the docs.xml files.

  gsk/gskmm/meson.build: dummy_header.h depends on all built .h files

  not just the used ones. Even the unused ones shall be built before
  the used ones are compiled. Used ones may #include unused ones.
  Should have been done in the previous commit.

  Gdk: Deprecate PixbufAnimation and PixbufAnimationIter

  GdkPixbufAnimation and GdkPixbufAnimationIter are deprecated
  since gdk-pixbuf 2.44.
  
  * demos/gtk-demo/example_images.cc: Don't use Gdk::PixbufAnimation
  and PixbufAnimationIter when gtkmm is built without deprecated API.
  * gdk/gdkmm/meson.build: Move pixbufanimation and pixbufanimationiter
  to gdkmm_deprecated_hg_ccg_basenames. Let dummy_header.h depend on
  all built .h files, not just the used ones.
  * gdk/gdkmm/wrap_init.h: Ignore deprecation of gdk_*_get_type()
  in Gdk::wrap_init.cc.
  * gdk/src/filelist.am: Move pixbufanimation.hg and pixbufanimationiter.hg
  to gdkmm_files_deprecated_hg.
  * gdk/src/pixbufanimation.[ccg|hg]:
  * gdk/src/pixbufanimationiter.[ccg|hg]: Deprecate.
  * gdk/src/pixbufloader.hg: Deprecate get_animation().
  * gtk/gtkmm/meson.build: Let dummy_header.h depend on all built .h
  files, not just the used ones.
