CL: Add some event/memory helper functions
Add the following helper functions on the CL frontend
- check for user event
- check for CL image/buffer types
And on the VK backend
- For CLBufferVk/CLImageVk much of the state is encoded in the
front-end object. Add utility functions to get handle to them.
- check for user event dependency in commandqueue
