pkg.m: Don't unload dependency packages when their dependers are loaded (bug #57522).
* pkg.m: Explain "-nodeps" option for "pkg load" and "pkg unload"; add one
more example with dependency.
* get_inverse_dependencies.m: New function.
* scripts/pkg/module.mk: Add get_inverse_dependencies.m to build system.
* unload_packages.m: rewrite parts of code; when checking input mention all
requested but non-installed packages instead of just the first; track down
loaded depender packages and if found, emit a sensible error message; process
handle_deps argument ('-nodeps').
* describe.m: Also display installed packages that depend on requested package.
