mergetool: break setup_tool out into separate initialization function

This is preparation for the following commit where we need to source the mergetool shell script to look for overrides before `run_merge_tool` is called. Previously `run_merge_tool` both sourced that script and invoked the mergetool. In the case of the following commit, we need the result of the `hide_resolved` override, if present, before we actually run `run_merge_tool`. The new `initialize_merge_tool` wrapper is exposed and documented as a public interface for consistency with the existing `run_merge_tool` which is also public. Although `setup_tool` could instead be exposed directly, the related `setup_user_tool` would probably also want to be elevated to match and this felt the cleanest to me.
