Implement the gamepad API in the IPC proxy

This does some reworking of the gamepad system to make it possible to hook in (previously it assumed that it was only talking to renderers) and I did some cleanup. Gamepad files were renamed to match the classes, and I did a bunch of test infrastructure work.

IMPORTANT BEHAVIOR CHANGE: This changes the Web gamepad API to report all gamepad data as soon as any of them are interacted with. This is what we need to do for Pepper anyway (since it gets all or none of the share memory) and I think makes more sense for most consumers anyway.

I separated out the user gesture detection code into a place where it can be used in the browser process as well, and exposed functionality in the gamepad provider to be notified when a user gesture happens.

The existing gamepad test was disabled and had bitrotted. This fixes it.
