Development/workerpool (#1741)

* [Tests/unit/core] : Fix build 'test_workerpool'.

'ThreadPool' and 'WorkerPool' changes were not (fully) integrated.

* [Tests/unit/core] : Amend 'a65dbb2adf2e9622aae8825c0d88c599a4a252e6'.

- Add 1 to occupation to compensate for the 'internal' timer.

- Reverse the boolean test for calculating occupation.

* [Tests/unit/core] : test for less or equal on timings in 'test_workerpool'.

Clock timings are never exact due to resolution, rounding and scheduling. Assume a Job executed earlier is allowed and preferred.

* [Tests/unit/core] : Disable instant job completion for 'test_workerpool'.

Time resolution and scheduling may prevent instant completion.

* [Tests/unit/core] : disable 'zero' delta times tests in 'test_workerpool'
