[REF] stock: cache the `get_warehouse` of `stock.location`

To avoid multiple search of the get_warehouse for the same location
and extra SQL request (it happens a lot for complicate flow, e.g.
mrp_mps, replenishment report).
Translate it into a standard compute to use the cache of
the ORM for no-store compute field (`warehouse_id`) and put
some depends to be always correct (even if `warehouse_id` shouldn't
change in the same request).
