1: Handle the inverse fields of `account.full.reconcile` manually
-----------------------------------------------------------------

In order to update the inverse fields of `reconciled_line_ids` and
`partial_reconcile_ids`, the ORM is triggering one query per full
reconcile record. In the case of a big batch payment, that is a lot of
round trips.
This also bypasses the computation for possible tracking, which is
expensive to do for 2 records at a time. That field is not tracked
anyway.

2: Batch the update of matching numbers
---------------------------------------

Basically the same as 1. without the tracking.

3: Batch the balance consistency test
-------------------------------------

Use the various context managers around `__reconcile_plan` to check for
the balance consistency only at the end in one single query. This avoids
checking it at every single intermediate write done on the lines.
Also doing it for the sync of dynamic lines. It should be useless but it
doesn't cost anything, and allows to remove the context keys in
enterprise without a cost. (they shouldn't be used explicitly, the
context managers should always be used instead)
Using these context managers also allows to remove all the `skip_`
context keys, which should not be used: using them will mean that as
soon as the journal entry is modified for any reason, some business
fields will change because of the synchronisation since the context
won't be the same anymore.
This commit therefore also makes `_sync_dynamic_line` more resilient and
avoids even more useless syncs.

4: Batch the construction of reconciliation batches
---------------------------------------------------

Introduce `_reconciled_by_number`, which is basically a `_read_group`.
In conjuction with `_filter_reconciled_by_number`, we can find all the
reconciled lines in one single query, for as many batches as needed; as
opposed to one query per batch before.

5: Precompute fields on partials
--------------------------------

Simply avoid doing one batched `INSERT INTO` followed by one `UPDATE` for
each record.

Benchmark:
==========

We are testing 2 use cases:
* a lot of small matchings that are producing a full 2 by 2
* one big matching (also producing a full)

To reconcile a batch payment of 500 (identical) lines in the bank reco:

|        | Queries |  SQL  |  Other |
|--------|---------|-------|--------|
| Before |    4191 | 4.649 | 16.253 |
|  After |     226 | 0.989 |  3.581 |

To reconcile one big batch of 1000 lines with the generic reco widget
(spaghetti):

|        | Queries |  SQL  | Other |
|--------|---------|-------|--------|
| Before |      82 | 0.478 | 1.131 |
|  After |      66 | 0.634 | 0.974 |

All the times are in seconds.
We can see the the use case of the batch payment is improved a lot (the
time is expected to be linear with regards to the number of payments),
while the time for big batches is not impacted.
