Project-Specific Debugging Helpers Support

I would like to request the addition of a feature that allows Qt Creator to load debugging helpers on a per-project basis. As far as I know, currently the only way to extend the debugging helpers provided by Qt is to manually add an extra Python script via Preferences -> Debugger -> Locals & Expressions -> Extra Debugging Helper.

This is inconvenient when switching between projects, as different projects may require different debugging helper scripts, and users have to manually change the script in the preferences every time.

It would be ideal if Qt Creator could look for debugging helpers within a specific directory in the project folder (e.g., .qtcreator/debug). If any debugging helper scripts are found there, they would be automatically loaded when the project is opened.

Proposed Behavior:

• Add a setting that allows users to specify a project-relative directory where Qt Creator should look for debugging helper scripts.
• When a project is opened, Qt Creator would automatically load any debugging helper scripts found in this directory.
• This behavior should be optional and configurable, so users who prefer the current system can still use it.
