config.h: install a stub replacement with a deprecation warning (bug #41027)

* Makefile.am (nodist_octinclude_HEADERS): Remove autoconf-generated config.h
from the list of header files to install.
* deprecated-config.h: New file to replace config.h in the public API.  Use a
different name to not shadow config.h during the build.
* libinterp/module.mk (install-deprecated-config-h,
uninstall-deprecated-config-h): New targets to install and uninstall it.
