[Backport] Wrong currency on creditmemo_grid & sales_order_view > creditmemo grid

[latenights]

Description (*)

Added missing column order_currency_code to table sales_creditmemo_grid. Copying column order_currency_code to sales_creditmemo_grid. Price column rendering changed on sales_creditmemo_index (Creditmemo grid) & sales_order_view - Creditmemo tab.

Manual testing scenarios (*)

1. Create order in different currency as configured on default store view
2. Go to Backend > SALES > Credit Memos, create Credit Memo
3. Check Refunded column on Credit Memo grid. You should see price in currency configured on default store view.
4. Go to Backend > SALES > Orders > choose your order and check Credit Memo grid in Credit Memos tab. You should see price in currency configured on default store view.

sales_order_view:

sales_creditmemo_index:

@latenights please report a bug report separately and fix in 2.3-develop first if it is reproducible.

@orlangur In M2.3 is also messed up. Different currencies (base currency code & order currency code). M2.3 Pull request created #22123

[orlangur]
