Added missing USB device descriptor fields needed for intent filters

The UsbDevice object is missing the ManufacturerName, ProductName, and
SerialNumber fields.  These are needed by intent filters to further
qualify a USB device that is plugged in while in host mode.  These
fields have been added in the jni UsbHostManager implementation and
propagated through UsbHostManager and UsbDevice implementations.
The UsbSettingsManager implementation has been modified to allow
manufacturer-name, product-name, and serial-number tags in intents.
