[FIX] l10n_fr: fix intra com, extra com taxes and fiscal positions

1. merge intra community taxes (one taxe with two report lines instead of two taxes with one report line each)
2. fix "tva à l'encaissement" fiscal position mapping (two rates were using the same xml_id)
3. add outside EU import taxes

closes odoo/odoo#49552
