[Feature request] Is there any config entry that can do OS specific Code Runner

[mcwindy]

From my humble opinion, it would be nice if an OS specific executorMap could be added. Maybe this OS specific config should have higher priority than the default one. For example, I want to use cl in Windows and clang++ to comile c++ in linux. I don't think turning off the config sync is a good idea, as well as using the vscode profile switching. eg: code-runner.OSSpecificExecutorMap.linux, code-runner.OSSpecificExecutorMap.windows or code-runner.OSSpecificExecutorMap.osx etc.
