platform/x86: Add Lenovo WMI Events Driver

Adds lenovo-wmi-events driver. The events driver is designed as a
general entrypoint for all Lenovo WMI Events. It acts as a notification
chain head that will process event data and pass it on to registered
drivers so they can react to the events.

Currently only the Gamezone interface Thermal Mode Event GUID is
implemented in this driver. It is documented in the Gamezone
documentation.
