Add uxTaskCallForEachTask, and refactor uxTaskGetSystemState to use it.

[DRNadler]

Get task statistics for all tasks with less memory use, by doing it one task at a time.

Description

Add uxTaskCallForEachTask, which is the iteration portion of last released uxTaskGetSystemState. uxTaskCallForEachTask calls a user-provided callback once for each task with a filled-in TaskStatus_t.

Refactor uxTaskGetSystemState so that it uses uxTaskCallForEachTask to fill in the pre-allocated array of TaskStatus_t, preserving the existing uxTaskGetSystemState API for current users.

Test Steps

1. Use uxTaskCallForEachTask to observe task statistics for each task in the system.
2. Compare existing uxTaskGetSystemState output to new version.

@DRNadler Thank you for your contribution. Could you please review my suggestion: aggarg_suggestion.patch.

This approach is very similar to yours, with the key difference being that it preserves the existing flow of uxTaskGetSystemState and avoids introducing an additional TaskStatus_t variable on the stack, ensuring we don't break existing applications.

Please note that I have not yet compiled or tested this patch, as I wanted to get your feedback first.
