auto detect available device when exporting (#1743)

Description
auto detect available packing device when exporting, priority: ["xpu", "cuda", "cpu"]

Expected Behavior & Potential Risk
When XPU format is required and XPU device is not available, INC will select packing device from ["xpu", "cuda", "cpu"] automatically.

How has this PR been tested?
test on cuda device when using xpu argument.
