Happens when device runs out of memory and Cycles is moving some textures to the host memory. The delayed memory free for OptiX BVH was moving data from one device_memory to another, leaving the original device memory in an invalid state. This was ruining the allocation map in the CUDA device which is using pointer to the device_memory. This change makes it so the memory pointer is stolen from BVH into the delayed memory free list. Additionally, forbid copying and moving instances of device_memory and added sanity checks in the device implementation. Differential Revision: https://developer.blender.org/D13316
