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
All of these variables that are being set in the constructor (`this._diagonstics`, `this._loggingOption`, etc.) are instance variables. Consequently, they will not be accessible in `send` because `send` is a static method rather than an instance method.

To fix this, we could make send an instance method and then instantiate and publish 1 telemetry object, like this:

```js
 _Base.Namespace._moduleDefine(exports, "WinJS.Utilities", {
  _Telemetry: _Base.Namespace._lazy(function () {
    var Telemetry = _Base.Class.define(function () {
      this._diagnostics = ...;
    }, {
      send: function () {
        if (this._diagnostics) {
          // ...
        }
      }
    });
    return new Telemetry();
  });
});
```
