It's not a specific state, it should be considered separately,
as a boolean.
This allows to reduce code complexity (flows should not rely (much) on
the locked logic) and to have a clearer flow.
Task-3163931
Part-of: odoo/odoo#115871
Purpose
=======
If the user doesn't have the timesheets app, it is not possible to generate
a task from an SOL. However, the user may want to generate a task without
necessarily timesheeting on it (e.g. a task in Field Service).
Specification
=============
Move the feature to a new module sale_project, sale_timesheet becomes
dependent on it.
