Meyer Jacobs b9f3c9c692 taggederror: Introduce taggederror-util for more ergonomic error tagging for eden error types.
Summary:
Introduce taggederror-util, which provides a new trait `AnyhowEdenExt`, which provides a method `eden_metadata` for anyhow errors and results. This method works much like `AnyhowExt::common_metadata`, but additionally supports extracting default error metadata from known `Tagged` types which are listed explicitly in the method implementation.

Extend `FilteredAnyhow` to support a configuration "metadata function", which allows swapping out `eden_metadata` for the standard `common_metadata`.

Modify Rust dispatch and Python bindings to use `AnyhowEdenExt` for metadata extraction and printing.

Modify `intentional_error` to rely on `AnyhowEdenExt` for tagging (removes `.tagged` call, no tags will be visible if `AnyhowEdenExt` is not used).
