[IMP] account: Store customer/supplier rank on partners

Purpose
=======

To correctly choose in which account a line should be posted,
we have to know if the partner is a customer or a supplier.

Specification
=============

Keep track of the number of account moves "in" and "out"
a partner has. These counts should be based on the posted
account moves. A customer that has been created from the
'Customer' menuitem will have a rank=1. When a customer
invoice will be created for him, the generated account moves
will be taken into account to compute its rank. The most
invoices we have for a partner, the higher his rank is.

Note: To avoid any concurrent update failures on the partner,
if one transaction has already locked a partner row, the count
update will be skipped that time.

This means the values may be approximative in the database!
The exact values will eventually be correctly computed at
the next successfull try.

Known limitation of this approach: The computation ignores
the set of currently selected companies. Actually, storing
context dependent values in the database is a bad practice,
and is avoided in that case by taking all the companies into
account.

Use the stored fields `customer_rank` and `supplier_rank`
to order partners when searching by name. This allows to show
best customers or best suppliers on top.

To choose if best customer or supplier are shown on top,
the context key `res_partner_search_mode` is used.
The context key can take two values: 'customer' or 'supplier'.
This decision partially reverts/revamps 8766f38 to only use
account moves instead of PO and SO

On actions showing partners, set a default filters to menus to
only display customers (customer_rank > 0) if the string is
"Customers", and only suppliers if the string is "Vendors" or
"Suppliers".
