[IMP] l10n_pe_edi: Improve sales invoice document type selection

The domain to document type on the invoice  has been updated to filter
based on the partner's identification type.

If the partner identification type is RUC, the default document type is
set to 'Factura', but allows assign Boleta if its necessary; for all other
partner identification types, the domain document type only allows 'Boleta'.
