LOG: [lldb][test] Add tests for printing references to C-strings

Printing references to C-strings doesn't work properly at the moment. This patch provides coverage for those cases and should fail once the underlying issue gets fixed (see https://github.com/llvm/llvm-project/pull/174398).

Added: 
    

Modified: 
    lldb/test/API/functionalities/data-formatter/stringprinter/TestStringPrinter.py
    lldb/test/API/functionalities/data-formatter/stringprinter/main.cpp

Removed:
