The query below
https://github.com/odoo/odoo/blob/81497125d8100c6bdd2dc30434232a88a419a3e3/addons/hr_work_entry/models/hr_work_entry.py#L92-L115


has bad performance without the bespoken indices on `date_start` and
`date_stop`. We can speed it up more with an index on `employee_id`.

This is not enough for DBs with many work entries (500K+), specially
during upgrades.

Here we optimize the query to take into account only the work entries
being modified.

This issue was observed during an upgrade saas~12.3->13.0 where the
payslip recomputation never ends due to the increased amount of hr work
entries created. Note how the first 1K payslips are processed in 1 hour
(~16 payslips per minute), while the latest 3 (before the upgrade
was killed) took 1 min.
