Remove Context from LightsManager constructor

Remove context from LightsManager as well as from its derived class:
InputDeviceLightsManager.
There aren't any usages of mContext in these classes.
Hence, InputDeviceLightsManager can be called from InputManagerGlobal
without any requirement of context to be passed.
The Managers can also be removed from the InputManager class.
