[SE] GlobalDeviceMemory owns its handle
Summary:
Final step in getting GlobalDeviceMemory to own its handle.
* Make GlobalDeviceMemory movable, but no longer copyable.
* Make Device::freeDeviceMemory function private and make
GlobalDeviceMemoryBase a friend of Device so GlobalDeviceMemoryBase
can free its memory in its destructor.
* Make GlobalDeviceMemory constructor private and make Device a friend
so it can construct GlobalDeviceMemory.
* Remove SharedDeviceMemoryBase class because it is never used.
* Remove explicit memory freeing from example code.
This change just consumes any errors generated during device memory freeing.
The real error handling will be added in a future patch.
