Add -fstandalone-debug debug flag (#104475)

# Summary

While debugging something in lldb, I found that the formatter I wrote for c10::intarrayref was not working correctly producing:
`(std::string) $6 = error: summary string parsing error`

Based off of this thread: https://github.com/vadimcn/codelldb/issues/415

I adde the standalone-debug information and fixed the std::string formatting issue.
