[Windows][PT2.6] Split larger Other Kernels lib (#1096)

torch_xpu_ops_sycl_kernels leads to around 1.83GB in size on windows,
splitting it to reduce the lib size.

New libs introduced in this PR:

torch_xpu_ops_sycl_tensor_srcs
torch_xpu_ops_sycl_norm_loss_srcs
torch_xpu_ops_sycl_poly_srcs
torch_xpu_ops_sycl_dist_srcs
