@brief Build a CAGRA index with a DLManagedTensor which has underlying DLDeviceType equal to kDLCUDA, kDLCUDAHost, kDLCUDAManaged, or kDLCPU. Also, acceptable underlying types are: 1. kDLDataType.code == kDLFloat and kDLDataType.bits = 32 2. kDLDataType.code == kDLFloat and kDLDataType.bits = 16 3. kDLDataType.code == kDLInt and kDLDataType.bits = 8 4. kDLDataType.code == kDLUInt and kDLDataType.bits = 8
