Convert HidDeviceInfo from a struct to a refcounted class.

Convert HidDeviceInfo from a struct to a refcounted class.

The HidDeviceInfo object for a device is passed around a lot, including
being copied every time enumeration of a device is requested. Since this
data is constant once a device is enumerated it is better to keep one
copy around for the device for as long as it is connected. This will
make it similar to the device::UsbDevice class.

I consider this a pre-requisite for storing more information in
HidDeviceInfo such as the raw report descriptor. Later patches will
revisit how this object is constructed and possibly reduce the number of
friend classes.
