Add thread renaming in async function handler (backport #550)

[mergify]

Description

Add thread renaming capabilities in async_function_handler

• by default, the component name truncated to 15 chars
• otherwise, configurable from yaml, alongside other async params

Tied to ros-controls/ros2_control#3482 , look there for explanation and demo

Did you use Generative AI?

Yeah, for the windows and macOS versions of thread rename. Used Gemini Pro. Did not test those versions, though.
