Update PythonZipper action to use CommandLineItem.CapturingMapFn

### Summary

This PR attempts to address #14890.

This updates the PythonZipper action to use a `CommandLineItem.CapturingMapFn` to defer expanding arguments until after analysis. I used `CapturingMapFn`, as it seemed like the only way to go about implementing the arg filtering that is done by the current code to exclude the `executable` and `zipFile` artifacts.

### Test Plan

Use the example from #14890 of looking at memory usage in tensorflow before/after this patch is applied on top of version `5.0.0`

Initial Setup
```
git clone [email protected]:tensorflow/tensorflow.git
cd tensorflow
python3 -m venv venv
source venv/bin/activate
pip install numpy
```

$ ~/code/bazel/bazel-bin/src/bazel aquery --build_python_zip 'mnemonic("PythonZipper", //tensorflow/python/...)' > /tmp/bazel_5_patched_out
$ diff /tmp/bazel_5_out /tmp/bazel_5_patched_out
# note: no diff output
