Revert of Refactoring gamepad polling to support dynamically added sources

Revert of Refactoring gamepad polling to support dynamically added sources (patchset #5 id:80001 of https://codereview.chromium.org/1586663006/ )

Reason for revert:
Some MSan bots started failing PepperGamepadHostTest.WaitForReply after landing this, I'm going to have to assume that it's related and look at it later next week.
