These changes lay a foundation for reusing more of Chez's
build process for Racket.

* gnu/packages/patches/chez-scheme-build-util-paths-backport.patch:
New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/chez.scm (chez-scheme)[source](patches): Use it.
[source](snippet): Remove bundled libraries here, not in configure phase.
[inputs]: Organize. Move "nanopass", "stex", and "xorg-rgb" to ...
[native-inputs]: ... this field.
[arguments]: Add (ice-9 ftw) to #:modules. Remove unneeded
'patch-processor-detection' phase. Add 'unpack-nanopass+stex' phase
(refactored from 'configure'). Simplify 'configure' phase by removing
patches that have been upstreamed. Add "--nogzip-man-pages" flag so we can
remove 'make-manpages-writable' phase. Stop ignoring #:configure-flags,
move "--threads" there, and remove unneeded workaround. Add 'prepare-stex'
phase (refactored from 'install-doc'). Use it to streamline 'install-doc'
phase, installing all of the right files into the right places.

[inputs]: Add newly required lz4 and lz4:static.
[arguments]:
 - Remove unused zlib symbol.
 - Since we are using ZLIB=, it looks like the substitution of libz.a path in
 .c/Mf-... files is no longer needed.
 - add lz4-static symbol and use new LZ4= and ZLIB= configure options to
   point to their static binaries.
