[MOV][ADD] sale_payment: bridge module between sales and payment

Move sale and payment bridge code into its own module. This commit mainly
moves (and reorganizes without changes) code from website_sale related
to payment and SO confirmation.

Only change is that payment_acquirer_id field on sale order is now a
related on transaction.acquirer_id . Indeed in website_sale and
website_quote both values were written but only managing transactions
and getting its acquirer is more efficient and ensure values are coherent.

JS part controlling payment form management is moved directly into
payment to reuse later on in future commits. Probably.
