feat(heap): Add feature to get peak heap usage

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.
