rnpletal: New package (#25154)

* rnpletal: New package

RNPL is an old package that is still used today by my collaborators, but doesn't see any development any more. I'm creating a Spack package merely to make it easier to install it on various systems. The code is not modern (C without prototypes – yes, that used to be a thing), and a large diff modernizes the code to make it palatable to modern C and Fortran compilers.

RNPL contains several sub-package. The current Spack package builds only the main one.

* rnpletal: Remove unused import

* Convert into AutotoolsPackage

* Don't check for "shared" variant

* rnpletal: Change "version" to `develop`

* rnpletal: Use existing `configure` function
