[ENHANCEMENT] Improved Handling of Failed Library and Variable Imports

[d-biehl]

To enhance the robustness of Robot Framework’s import mechanism, we propose improvements for handling failed library and variable imports. The key improvements are as follows:

1. Enhanced Failure Detection and Response:

   • Upon an import failure, attempt to analyze the root cause (e.g., missing files, incorrect paths, or network issues for remote libraries).
   • Provide more descriptive error messages or suggest potential resolutions based on the detected issue.

2. Intelligent Retry Mechanism:

   • Avoid re-attempting failed imports during the same execution if the library meets certain conditions:
     • If it is a dynamic library (one that depends on runtime conditions).
     • If the failure is due to a timeout (e.g., network-related issues).

3. Quickfix Option for failed imports:

   • Introduce a quickfix mechanism to allow users to update and retry the import of only the affected library.
   • To add a library to a permanent cache
