Fixes to the DAG path visualizations

[zilto]

The viz would display the set of nodes + their immediate parents. The driver function would only pass the "nodes on the path" and have the viz draw the parents.

This caused an issue because nodes not explicitly passed didn't received styling. Instead, they were implicitly created when trying to create to them.

Changes

There are 3 sets of changes:

1. Create_graphviz_graph(): added logic to highlight path in red
2. Driver visualizations: expose the new params (show_legend, orient, hide_inputs, deduplicate_inputs) to all visualization functions
3. Path visualizations (between, upstream, downstream): The changes force the parameter strictly_display_only_passed_in_nodes=True and handles the nodes to pass at the Driver level (i.e., includes the parents explicitly).

How I tested this

The existing test suite still works. Changes only affect how the set of node is passed from the Driver to the create_graphviz_graph() function and how nodes / edges are displayed.

Checklist

• PR has an informative and human-readable title (this will be pulled into the release notes)
• Changes are limited to a single goal (no scope creep)
• Code passed the pre-commit check & code is left cleaner/nicer than when first encountered.
• Any change in functionality is tested
• New functions are documented (with a description, list of inputs, and expected output)
• Placeholder code is flagged / future TODOs are captured in comments
• Project documentation has been updated if adding/changing functionality.
