Fix QEMU download URL - update to esp-develop-9.2.2-20250817

The old URL (esp-develop-20220919) was returning 404 errors.
Updated to use the latest stable release with correct URL format:
- Release tag includes date suffix (esp-develop-9.2.2-20250817)
- File path includes version in filename
- Binary location changed to bin/qemu-system-xtensa
- Added fallback URLs for older versions
- Added symlink creation for backward compatibility
