gh-151946: Fix Sphinx reference warnings in logging.handlers

[BHUVANSH855]

Summary

Fix Sphinx reference warnings in Doc/library/logging.handlers.rst by updating ambiguous cross-references to fully qualified references where appropriate and marking implementation-specific names that should not be cross-referenced.

The changes include:

• Qualifying references to logging classes and constants.
• Qualifying I/O method references to the appropriate io base classes.
• Marking implementation-specific methods and attributes with ! where cross-references are not intended.

Issue

gh-151946

Testing
