[FIX] mrp: change dependency of related field

Browse Source 
Fields `product_qty_available` and `product_virtual_available` on
stock_move are related on quantities fields of move's product_id. On
large database, those two fields will slow down every transactions that
updates stock move state (confirmation, validation, ...).

`state` on stock.move is a dependent field of computed field `qty_available` on
product.product which is dependent field of related field
`product_virtual_available` on stock move. This relation tree implies
that updating the state on one particular stock move will mark its
product (qty_available) as 'to be recomputed' and thus **every** stock
moves (product_virtual_available) of this product as to be recomputed.
On database will 100k+ stock move per product. Fetching all stock move
of some products take 90% of a manufacturing order validation time. This
is problematic knowing those two quantity fields are only used in the
stock move tree form so computed anyway at the view rendering.

This commit change the `depends` of those two related field to mark them
as to be recomputed only if the product_id change.
