bluetooth: Remove test support for the non-WinRT low-energy backend

The next change will remove support from Bluetooth Low Energy from
BluetoothAdapterWin. This change removes the support code from
BluetoothTestWin.

This code is unnecessary because the non-WinRT BLE backend was never
enabled by default and was only ever intended to support Windows 7 and
8, which are no longer supported by Chrome.
