Logging Service does not allow for setting log level on a global level

[capnkenny]

Basically, even when setting the logging info on a new logging service instance, it only sets the logging level of the logger that is created. Therefore, you can't effectively disable debug logs on a debug build - it'll only disable (atm) if you build the engine in Release configuration.

Repro Steps:

1. Build NovelRT in Debug
2. Build InputEcsSamples in Debug
3. Launch InputEcsSamples (Review Console Output)
4. Build NovelRT and InputEcsSamples in Release
5. Re-run InputEcsSamples (Review Console Output again)

I would expect that even in Debug mode, the logging would respect the setting defined in the application's main.cpp (or wherever the setLogLevel function is being called.
