Make non-static LogManager class accessible through WinRT

[kagillig]

Is your feature request related to a problem? My team works on a UWP app that needs to be able to change the collector URL. However, only the static LogManager is available right now and it doesn't appear to be working with this implementation. Therefore, we'd like to be able to use the non-static LogManager instead.

Describe the solution you'd like. We've been informed that non-static LogManagers are already supported by the core C++ layer of 1DS C++, but it is not accessible through WinRT yet and changes nedd to be added here: [https://github.com/microsoft/cpp_client_telemetry/tree/main/lib/shared](https://github.com/microsoft/cpp_client_telemetry/tree/main/lib/shared)

Describe alternatives you've considered. We considered using the static class, but are running into issues.
