Subject: [PATCH] [IMP] l10_dk_bookkeeping: rate at transaction

Following the Bookkeeping Act Request we needed to have the conversion rate at
the time of the move (only when having a move with a currency different as the
one of the company) on the header of the form view.

This pr will add a new compute stored field, that will be displayed on the
header of the move only when the current company is Danemark, when the company
currency is different as the move currency and if there is at least a line.

The information we will display is the currency_rate of the first line since on
invoice and bill the currency_rate is the same for all the lines.

We also added a related on account_move_line to be able to see the rate on the
journal items list view.

closes odoo/odoo#141954
