build-system: Add 'channel-build-system'.
* gnu/ci.scm (channel-build-system, channel-source->package): Remove. * gnu/packages/package-management.scm (channel-source->package): New procedure, moved from (gnu ci). * guix/build-system/channel.scm: New file, with code moved from (gnu ci). * doc/guix.texi (Build Systems): Document it.

This variable is exported by @code{(guix build-system channel)}.

This build system is meant primarily for internal use. It requires two

arguments, @code{#:commit} and @code{#:source}, and builds a Guix
|

instance from that channel, in the same way @command{guix time-machine}
