task: use get_task_name where possible

[XuNeo]

Summary

Introduce get_task_name to streamline code by replacing (#if #else #endif) with a cleaner implementation.

Impact

For debug log, instead of printing nothing, now it will print "noname".

Testing

CI test should be enough for this change.

This PR appears incomplete based on the NuttX requirements.

Here's why and what's missing:

• Summary:

  • What functional part of the code is being changed? Be specific. Mention the affected module(s) or file(s).
  • How does the change exactly work? Explain the mechanism of get_task_name and how it replaces the #if/#else logic.

• Impact:

  • Impact on user: While seemingly minor, changing debug output can impact users. Be explicit:
    • Will existing user scripts break?
    • Is "noname" the appropriate output, or should it be configurable?
  • Impact on documentation: Even small changes often need documentation updates:
    • Is get_task_name documented somewhere?
    • Do existing code comments need adjustment?

• Testing:

  • CI is NOT enough. You need to provide specific local testing details:
    • Build Host: At least one OS/CPU/compiler combination
    • Target: At least one architecture/board/configuration
  • Testing logs: While "before" logs might be trivial, you MUST include "after" logs demonstrating the change in output.

In short: Don't assume reviewers understand the context. Provide enough detail to make the PR's value and correctness immediately clear.
