Update XML IDs references for arguments of some built-in methods in Odoo 16

[trinhanhngoc]

The Odoo plugin supported XML IDs references for some built-in methods such as: xmlid_lookup, xmlid_to_res_model_res_id, xmlid_to_res_id,... However, in the commit c7bac3dee (Odoo 16), Odoo made these methods private, so the Odoo plugin also needs to be updated to support them.
