Layer Panel should scroll to the selected layer when selecting in viewport

When selecting layers in the viewport, the Layer Panel should scroll and expand groups until the layer selected is evident. This should be true for the Select Tool _and_ the Path Tool.

Why? It provides context as to what you are selecting without having to scroll around in the layer panel. This allows a more _viewport_ focused navigation style along side our currently _layer panel_ heavy navigation style for large documents.

Users naturally interact by trying to select things that are visibly in the viewport first, then if that fails they try to go dig through the layer panel. This often results in an "_eyes look at shapes_ -> _eyes scan layer panel and try to select_ -> _eyes look at shapes_" loop that isn't ideal for discovery. It would be better if the state of the world remains synced across all representations of the document, so it isn't confusing as to _what is what_.

This is meant to go along side #2818.
