Allow enabling experimental hardware plane support 

Hardware plane support is inactive unless a scanout handler is set, this
patch adds a scanout handler and uses it when the env var
E_USE_HARDWARE_PLANES is set.

In the future this env var will go away when hardware plane support is
stable enough to enable it everywhere.
