This PR adds some new state to the LibraryContainer and some conditional rendering to the LibraryItem based on props from the LoadedType data.

LibraryContainer.State.HostContext is essentially an enum that can be used from the Dynamo side to let LibrarieJS know what context it's being displayed in (home workspace, custom node workspace etc)

LibraryContainer.State.shouldOverideExpandedState also controls the rendering behavior of LibraryItems - I found that LibraryItems today use a legacy life cycle hook UNSAFE_onWillRecieveProps - to override state with props - specifically for the expanded state so that when interacting only one library item can be open at a time.

This hook also makes it so that when the UI is rendered the currently open item will close. Sometimes this is not desirable like when switching between workspace contexts, so I added some new state which is essentially a mode to control this behavior - currently we turn off the behavior only when switching contexts, so that library items retain their expanded state during the context change render.

LoadedTypes now have hiddenInWorkspaceContext which determines if they are hidden in the home workspace context.

I could not figure out how to add a test for this behavior but it seems straight forward for someone familiar with jest/enzyme - I am out of bandwidth and will file a task for it.
