[lldb][test] Combine libstdc++ and libc++ std::string tests into generic test (llvm#147355)
This combines the libc++ and libstdc++ test cases. The main difference was that the libstdcpp tests had additional tests for references/pointers to std::string. I moved those over. The libstdc++ formatters don't support `std::u16string`/`std::u32string` yet, so I extracted those into XFAILed test cases. There were also two test assertions that failed for libstdc++: 1. libstdc++ doesn't obey the capped/uncapped summary options 2. When a summary isn't available for a std::string, libc++ would print "Summary Unavailable", whereas libstdc++ just prints "((null))". This may be better suited for the STL-specific subdirectories, but left it here for now. I put those in separate XFAILed test-cases. Split out from llvm#146740
