Collapse multiple USB device manifest permissions into a single entry.

Like the hosts permission messages an app can request access to a
single kind of USB device (identified by vendor and product ID pair)
or many different kinds of devices. In the latter case Chrome
previously listed only one of the requested devices, hiding the rest.

This patch follows the example of the hosts permission messages and
provides two different message formats; one for a single USB device
and one that indicates access to multiple devices is permitted and
includes the full list in the details string. As there may be
permissions involving devices without a known vendor and/or product ID
special strings for "devices from vendor A" and "devices from an
unknown vendor" are provided. These messages are de-duplicated as
necessary.

As it provides no additional information the general "Access your USB
devices" message associated with the "usb" permission has been removed,
following the example of there being no message associated with the
"fileSystem" permission. An app with this permission can this use the
chrome.usb.getUserSelectedDevices function to request access to a
particular device at runtime. This device will then be listed in the
app's permissions and be revocable.
