This change moves the GamepadSharedMemoryReader class to
third_party/blink/renderer/modules/gamepad. Its instance is now
created in relevant Device*Dispatcher methods with a LocalFrame*
passed to be used for Mojo interface creation.
Since the GamepadMonitor interface request is now made on a frame, its
registration was moved to RenderFrameHost and
content_browser_manifest.json was updated accordingly.

Blink-related updates:
- DISALLOW_COPY_AND_ASSIGN -> WTF_MAKE_NONCOPYABLE
