Simplify cpp checker bundle example and update cpp baselib

[hoangtungdinh]

Description

This PR simplifies the C++ checker bundle example and makes it output proper rule UID. This is to prepare for replacing the C++ text report with the Python text report, in which stricter enforcement of rule UID format is required. See #191 .

Also remove methods in the C++ baselib that allow users to create Issues without Rule UID.

Note that, the C++ baselib still doesn't have strict enforcement for rule UID format and for rule registration.

Main changes

1. Remove the option --default_config from the C++ example checker bundle.
2. Remove the option to call the C++ example checker bundle directly with a .xodr file as input. Now, the C++ checker bundle only accepts a configuration file as input.
3. Update the test configuration for the C++ example checker bundle.
4. Set proper rule UID for checkers and issues in the C++ example checker bundle.
5. Remove methods that allow users to create issues without a proper rule UID in the C++ baselib.

How was the PR tested?

1. Unit-test.
2. Runtime test using the test pipeline in the Python qc_framework.
3. Load the generated .xqar result from the C++ checker bundle using qc_baselib. The results can be loaded successfully.

We could do much more, make it nicer, .... but yes, not as part of this PR for preparing the release.
