docs: adjust for demise of scripts/create_config

The config-host.h, $TARGET_NAME-config-target.h,
$TARGET_NAME-config-devices.h files are now generated by
configure_file() rather than scripts/create_config.  Adjust
he relevant paragraph in docs/devel/build-system.rst, and take
the occasion to fix a preexisting confusion of *.h vs *.mak.
