[IMP] mrp_multi_level: enchance traceability with origin.

* keept description of planned orders verbose.
* make it translatable in most cases.
* while grouping demand include the product in the description.
* add `origin` field not mrp moves and planned orders. Fill it
  with top level demand origin.
