This feature keeps track of the per task peak memory usage. - Update the heap_task_tracking example to make use of the new feature Cleanup the implementation: - multi_heap_get_free_size() is never used, remove it. - Minor update in heap_caps_update_per_task_info_xx() funcitons. - Update settting on block owner in heap_caps.c to work with the get peak usage feature. - Update heap_caps_update_per_task_info_free() to detect when it is called to delete the memory allocated for a task TCB. Mark the corresponding task in the statistic list as deleted. - Add a Kconfig option dependant on HEAP_TASK_TRACKING being enabled that force the deletion of the statistics related to deleted task when set to true. - In task tracking feature, add a current and peak memory usage to the heap_stat_t structure to keep track of the current and peak memory usage of the given task across all heaps. - Fix missing block owner when allocating memory for heaps_array in heap_caps_init. - Keep the original implementation of the task tracking for backward compatibility reasons.
