gnu: Add chez-nanopass.

* gnu/packages/chez.scm (nanopass): Rename to ...
(chez-nanopass-bootstrap): ... this new variable, and promote it from an
origin to a package.
(chez-nanopass): New variable.
(unpack-nanopass+stex): New variable using 'chez-nanopass-bootstrap'.
(chez-scheme-for-racket-bootstrap-bootfiles)
(chez-scheme)[native-inputs]: Add 'chez-nanopass-bootstrap'.
[arguments]<#:phases>: Adapt 'unpack-nanopass+stex' phase
to use the new variable.
* gnu/packages/racket.scm (racket-vm-cs): Likewise.
(make-unpack-nanopass+stex): Remove it.
