[FIX] purchase, purchase_stock: add price difference account

Version 16.0 removed the price different account following this pull request #99411

This decision has been made because it was only used anymore by standard cost method and real time valuation.
We thought that standard was not a valid accounting method and we didn't want to maintain code for it.

But:
- Standard could be valid if you manualy complete the accounting entries
by yourself (e.g. employees/machines cost in mrp).
- It's also valid if you record the difference between standard price and
vendo price (price diff)

If you want to have an estimation of your cogs (benefits and loss) during an
accounting period. People just do a manual correction at the end but they have
a real time reporting on the situation.

It's a too big regression to be acceptable. We apologize and reintroduce it for
16.0 and future version.

This PR reintroduce the fields in purchase and the fix module in 16.0 is
not needed anymore.
