Add telemetry collection code to Winjs to be used in Microsoft WinJS fra...

...mework package.

2 files are added:
1. _telemetryImpl.js - which will be used when building Microsoft WinJS framework package
2. _telemetry.js - the default no-op file
Using `_moduleDefine(exports, ...)` like this going to cause us to end up with an extra property. The snippet below illustrates what I mean.

```js
define(['./Utilities/_Telemetry', function (_Telemetry) {
  // We'll end up with code like this
  _Telemetry._Telemetry.send(...);

  // Instead of like this
  _Telemetry.send(...);
});
```

@xirzec What's the best practice for fixing this?
