Add unified-selection-react package

[grigasp]

Closes #829
Closes #830

This probably should've been at least 2 PRs, but there was a lot of back and forth, and I didn't want to waste time splitting them afterwards.

The new package now provides a React context that other packages can use, so consumers don't need to have a separate provider for each package. However, I also made changes in hierarchies-react and components to consume selection storage through a prop rather than context, so the context is only used by InstanceKeyValueRenderer, which has no way of getting the selection storage through prop.
