Make fx.Transformer.get_attr call tracer to preserve node.meta (#95245)
Currently, transformer creates proxy objects directly for get_attr method. node.meta is lost in this step. In order to keep it, we invoke tracer.create_proxy. Meta data is copied over in tracer.create_proxy and tracer.create_node.
