gnu: chez-scheme: Update to 10.0.0.

* gnu/packages/patches/chez-scheme-bin-sh.patch: Refresh patch.
* gnu/packages/patches/chez-scheme-backport-configure.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/chez.scm (chez-scheme): Update to 10.0.0.  Inherit from
'chez-scheme-for-racket'.
[source]<patches>: Use "chez-scheme-backport-configure.patch".
<snippet>: Also unbundle Zuo.
[native-inputs, native-search-paths, outputs, arguments]
[supported-systems]: Inherit from 'chez-scheme-for-racket'.
[inputs]: Likewise, replacing the bootfile package and adding libx11.
[description]: Update based on the User's Guide, release notes, man
page, and README file.
(chez-scheme-bootstrap-bootfiles)[supported-systems]: All systems are
now supported.
(chez-scheme-for-system): Return 'chez-scheme', since it now supports
all systems.
