Steps to reproduce:
-install l10n_sa_invoice module
-switch to a company in Saudi Arabia (SA company)
-create and print an invoice with a product that has arabic translation

Bug:
When adding a product and the Arabic translation.
If we add an internal reference it is added to the template,
Odoo directly concatenates this with the product name.
The result is the product name being duplicated.

Fix:
display line name and add the translation if it's different

We did not add the description of the invoice line on the print-out
of the invoice. (probably because description is not translatable
and the name of the product is)

If a product is set, the name of the product becomes the description (label)
on the invoice line,  but of course this depends on the language.

So, we only add the description if it does not correspond
to either the English (/standard language) or Arabic product description.
(People can always add both languages in the same field)

Of course, if the product is not set, it will also just show the description (label).

Also put the : of the payment reference in Arabic on the other side.

[FIX] l10n_gcc_invoice: fix traceback on invoice when a section is present + fix arabic display on the section subtotal

having a section or a note on the invoice would trigger a traceback when printing the invoice for a GCC company. The arabic/english label inside that element would not display properly either

Most GCC countries are required by law to have invoice reports in both arabic in english
