Fix USB discovery on Windows in case there is no USB port

Fix #4993

This is not tested.

Pull Request Overview

This PR fixes a bug in Windows USB serial device discovery where the application would crash when no USB ports are present. The fix wraps registry access calls in try-catch blocks to handle RuntimeExceptions gracefully.

• Added exception handling around all Advapi32Util.registryGetKeys() and Advapi32Util.registryGetValues() calls
• Added debug logging for registry access failures
• Returns empty results or continues processing when registry operations fail

I never saw a Windows PC without a USB port, so would not know how to physically test it. However the code LGTM.

You can disable USB ports in the BIOS or in the device manager or not install the device drivers. Old PCs also don't have them. 😄

What is your feeling about Copilot suggestion ?
That is true that I could use com.sun.jna.platform.win32.Win32Exception

I think any exception is bad. So you should catch and log them all. Trying to double guess what detail exceptions may or may not be thrown, on whatever machine and OS it may be, seems like an invitation for another user to open another issue at sometime. Just catch them all..

I finally applied Copilot suggestions after checking the code of Advapi32Util.registryGetKeys and Advapi32Util.registryGetValues.

Thanks!

A backport to 5.0.x is probably recommended.
