If we want to go down this path, I think we should make `Host::SystemLog` a noop on windows (until someone comes up with a better implementation)

Regarding limiting the output, I'm happy to draw the line at `LLDB_LOG_ERRORV`. The system log is pretty cheap on our platform and I assumed it's the same on Linux, so personally I would hope it doesn't deter anyone from using `LLDB_LOG_ERROR`. 

@adrian-prantl do you want the system log to include the dropped errors in `Status`. If so we'll need to promote that to use `LLDB_LOG_ERROR` instead.
