[16.0][IMP]analytic_mixin_analytic_account and stock_analytic

[arnaudlayec]

analytic_mixin_analytic_account

Make it compatible with other module account_financial_report of OCA/account-financial-reporting
Just add compute_sudo=True to both fields analytic_account_ids and analytic_account_names, so that the console does not throw the error account.move.line: inconsistent 'compute_sudo' for computed fields: analytic_account_ids, analytic_account_names
Indeed this last module also computes a field analytic_account_ids with `store=True

stock_analytic

Add a _compute_analytic_distribution method, quite generic, to apply by default the analytic distribution model at stock.move creation, like on any other object using analytic (purchase order, invoice, ...).

Sorry for the 2 commits of different modules in the same PR, it was not intentional and I did not find how to easily correct this
