add dynamic shape and full graph support
Summary: I believe it has value to test out those two flags - dynamic shape is something pretty common but may not show up in torchbench because it uses the same data. Forcing dynamic shape/symint will go a different code path which reflects the real perf. Otherwise we may end up with a pretty big gap https://fb.workplace.com/groups/751705896147977/posts/785994219385811.
