    Make quiet installations possible
    
    * util/build_scripts/doc-reference.py:
    * util/build_scripts/generate-binding.py:
    * util/meson_aux/extra-install-cmd.py: Don't print names of installed
    files or other informative messages if the environment variable
    MESON_INSTALL_QUIET is set.
    It is set by "meson install --quiet" in Meson 0.54.0 and newer.
