Block some HID devices from chrome.hid.

This blacklists some specific types of HID devices from
being accessible to the chrome.hid API. Namely, any keyboard,
mice, other pointer devices, or system control inputs (such as
power and reset buttons) are blocked and cannot be enumerated
or opened by the consumers of the API.
