[Inductor] support channel last for xpu conv in inductor layout opt path

[guangyey]

Motivation

support xpu channel last for inductor layout optimization path.
Currently, _conv_determine_backend_memory_format always returns torch.contiguous_format for XPU conv.

Solution

Add xpu channel last detection stragey in determine_backend_memory_format
