- Introduce a new account.tax.report object
> Tax report lines now refer to a tax report, and the tax report to a country
- Tax report lines can share tags accross reports within the same country
> To support the cases where some report is a simplified version of another one: some of its lines can be computed in the same way as the 'bigger' report.
> This is done by giving the same tag_name to the tax report lines, and the same country_id to their parent report.
> Full support for tag name modification, and the way it impacts the shared tags (sometimes, we can overwrite them all, sometimes we must delete them, sometimes, we create new tags to replace them on some report lines).
- Support copying tax report (and the lines/tags linked to it), so that it is possible to duplicate them and change the country set on the duplicate for use in another country (coopying is way better as replacing in place, as we don't keep any link to an xmlid, and still allow using the original report in the original country it was created for).
- Make all l10n* modules compatible with those changes

[IMP] l10n_*: don't define accounts or tags on tax repartition line templates anymore for 0% taxes
[FIX] account: remove old function used to migrate the former tax model, incompatible with the new one
- Add repartition lines on taxes
- Link account tags directly to account.move.line; remove the tag_ids field from account.tag
- Add a new report engine dedicated to tax reports, directly generating account tags. It is called as an alternate mode of generic tax report, with a dedicated "Use tax grids" toggle.
>> The biggest change lies in the way the new tax report computes its values.
Everything is now aggregated directly using the tags set on the account move lines. Thanks to that,
modifying the configuration of a tax today will not impact the report for the previous periods anymore.
This is a big improvement, as it means the report will keep on reflecting the values that were submitted
to the state before, whatever the configuration change.
- Add an audit char field to account.move.line telling with tax grids are impacted by the line, with the corresponding amount
- Modify the behavior of cash basis taxes: the cash basis account is now used as the transition account, while the regular account given in tax declaration is used to store the final entry (it was the opposite before)
- Modify every l10n_* module in order to keep them consistent with these changes
