Add libyaml module definition (#1104)

* Add libyaml module definition

* fixup

* s/yaml/libyaml/

* add bazel matrix

* add (no) maintainers

* fix config_h template

* Fix to use defines instead of template

as that's not available in the release archive (only in source)

* Fix MODULE.bazel

* not sure what's up with windows, leave it out for now
