[FIX] l10n_latam_base: identification type default

Identification type  was always been overwrite by the _onchange_country even when just opening the contact form, this was always setting the is_vat identification type as default without taking into account if the user has defined their own default.:
* If Identification type is set and it is compatible with the country then we leave it as it is (this is the case the identification type has been set by a default).
* If Identification type is set but is not compatible with the country then compute and set the Identification type that is is_vat True for the country

Where country is the one set in the partner record, if not set will use the country of the move's company, if not defined then will use the country of the environment company
