wake lock: Use WakeLockContextRequest instead of InterfaceRequest<WakeLockContext>

This has no visible effects and is just a change to improve readability.
Follow the format used by most code and use

    mojom::WakeLockContextRequest

rather than the more verbose

    mojo::InterfaceRequest<mojom::WakeLockContext>
