Update `pass_manager` to handle updating the cached shape when submodule shapes change

[CharlieL7]

• Extend code in pass_manager.cpp:run_passes(prog, root_mod, passes, trace) to handle updating the cached shape from op.compute_shape(shape_inputs, mod_inputs) when mod_inputs shape changes.
  • Currently, the cached shape is not updated when submodule inputs have their output shape changed.
  • Can probably be implemented by keeping track of the parent instructions that need to be updated after all submodules are updated.
• Remove the simplify_select_module_output_shape matcher and pass from simplify_dyn_ops.cpp. Move the shape computation logic into select_module.compute_shape().
