## Context
After reimplementing the task stream filter in Airflow 3, a feature request was raised by @bbovenzi to add a level parameter in this filtering functionality. In this way, a user could more easily "traverse" a complex DAG when debugging. It will also be easier to see direct dependencies on the more dense nodes.

Related: #58450

## Examples

Besides the added test, I hooked it up to the frontend to give the reviewer a bit more of an idea of what's happening:

With root `section_1.task_3` and depth 2:

With root `section_1.task_3` and depth 1:
<img width="1145" height="714" alt="image" src="https://github.com/user-attachments/assets/c88ae5c8-b293-4b31-ae5c-88cdb99e7ef6" />

## Note to Reviewer
I found some odd behaviour in the frontend when setting depth 0. The singular task is correctly shown, but keeps rerendering until it disappears. This behaviour **only** happens on depth 0. Depth > 1, it works perfectly well.

The tests pass, and following the code, I find I get the expected results. Not sure if this is a bug in the frontend. Thought it would be good to mention it at least. I considered setting the minimum accepted value at 1 but I feel 0 should be accepted too.

Happy to discuss further.

## Testing

I created two scenario's which should show the reviewer the behaviour on a small scale and help verify the functionality. Let me know if there is any need to further elaborate on this.
