Summary:
Reason for this change:
(1) Setting/Getting default gpu id doesn't seem to be used at all.
(2) It actually is confusing compared to the CUDA_VISIBLE_DEVICES options etc.
(3) When setting cuda_gpu_id=-1 in the CUDAContext arg, it used to use the
default gpu id but probably we should use the current gpu - so that the caller
will be able to control the device placement.
One use case is for TensorRT - if we have a custom callback layer, then it would
be easier for TRT or whatever caller to set the running device.
