[REF] purchase_*: change received qty api

The received quantity on Purchase Order line can be compared
to the delivered qty on Sales Order line. It is now time for
both to share the same mecanism (introduced in
3bf8a62e0dd99f7dad42718f895abf4fd53f996f).

This commit sets `qty_received` as a computed field, depending
of a method (`qty_received_method` field) to compute it. The
value can be computed based on
 - manual value; for services (all the time), and consummable
 products (when stock is not installed).
 - stock moves; for stockable and consummable products (when
 stock is installed)

This is now easier to extend the way the received quantity
need to be computed (like in sale).
