[ADD] sale_project: Move task generation from SO feature

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.

Task-2123707
