freertos: Synchronize vTaskPlaceOnEventList...() functions to v10.4.3

Browse Source 
This commit synchronizes the following vTaskPlaceOnEventList...() with
upstream v10.4.3.

The functions updated are:

- vTaskPlaceOnEventList()
- vTaskPlaceOnUnorderedEventList()
- vTaskPlaceOnEventListRestricted()

The traceTASK_DELAY_UNTIL() macro has also been updated.
