services: xorg: Define an <xorg-configuration> record type.
* gnu/services/xorg.scm (<xorg-configuration>): New record type. (xorg-configuration-file): Remove. (xorg-wrapper): Remove #:modules, #:configuration-file, and #:xorg-server; add optional 'config' parameter instead. Adjust accordingly. (xorg-start-command): Likewise. * doc/guix.texi (X Window): Document 'xorg-configuration'. Update 'xorg-start-command' documentation. Remove 'xorg-configuration-file' documentation.
