Implemented BluetoothAdapterWin::IsPowered().

I didn't include SetPowered() implementation here because SetPowered() requires a reference to bluetooth adapter handle and right now that is only created within the polling method. I will refactor this in the next CL to have BluetoothAdapterWin hold a bluetooth adapter handle pointer so that we can call SetPowered() using it.
