Create ops with static shapes in PadTensorOpConversion if they're static (#5516)

Currently, the mhlo.pad will be lowered to linalg.pad_tensor and then
lowered to `linalg.init_tensor + linalg.fill + subtensor_insert`. The
init_tensor op will produce a dynamic shape even if the shape is static.
This leads a `tensor.cast` op added and relies on further patterns to
fix them. This is not needed to static shape and will hit some issues
related to https://github.com/google/iree/issues/5385.
