Added some debugging instructions for debugging a StackOverflow on Windows and made some minor improvements to the pre-existing text. Unfortunately the Windows and Linux instructions remain asymmetric because the dump debugging experience for StackOverflow on Windows isn't good (dotnet/diagnostics#4944). In the future we might also want to add instructions for using VSCode on Linux or add more to the lldb debugging instructions but I didn't want to expand the scope too much for now.

On Windows if an application crashes with a stack overflow and a dump is collected, looking at it in both Visual Studio and windbg gives little clue about the callstack which caused the overflow.
For repro and observed behavior, see #3506. #3506 tracks improving the documentation, this issue tracks improving the actual product experience.
The desired behavior is that both VS and windbg should prominently show that a StackOverflow occured and show the callstack frames that ran recursively to cause the overflow.
