Add a runtime event for detecting EventSourceSwitch turned off #47062

For ETW/LTTng scenarios - if EventSourceSwitch is turned off, tools that relies on OS-specific tracing mechanisms like ETW/LTTng can't use diagnostics server command to detect that EventSourceSwitch is turned off for a target app.

This issue tracks work for adding a runtime event under the Microsoft-Windows-DotNETRuntime provider that always fires when EventSourceSwitch is turned off.
