[fx][passes] Implement annotate getitem node FX passes (#90237)
Summary: One common cause of jit unscriptability issue is loss of node type annotations on local names after one or several FX transform(s). One way to improve the type coverage is to eagerly annotate the type for `getitem` nodes from its parent sequence node. This diff introduces an fx pass to do that.
Test Plan:
```
buck2 test //caffe2/test:fx_experimental
```
