feat(freertos/idf): Add config option for FreeRTOS Timer Task core affinity
This commit adds the ability to set the core affinity for the FreeRTOS Timer Service task when multi-core configuration is enabled. This commit also adds a Kconfig option to set the core affinity of the timer task via the menuconfig. Closes https://github.com/espressif/esp-idf/issues/10315

|
||||
### tasks.c
|
||||
|
||||
- Backported a change where the IDLE tasks are created with the core ID as a suffix in the task name.
|
||||
|
||||
### timers.c
|
||||
|
||||
- Backported configTIMER_SERVICE_TASK_CORE_AFFINITY config option to enable configurability of the Timer Service task's core affinity.
|
||||
- The change also entails updating the task creation APIs to use IDF-FreeRTOS task creation APIs, adding a assert check for valid affinity values and dropping the use of configUSE_CORE_AFFINITY.
