`ManageOperationalLayers` fixes

[williambohrmann3]

Description

• Resolves a bug which prevented the visibility of the excluded layers list.
  • Accomplishes this by moving to CollectionView.
• Uses Calcite UI icons for buttons.
• Adds clarity to sample directions.

Note on promotion and demotion of layers

Promote and demote language now refers to the draw order, not where the layer falls in the vertical hierarchy of the list view. This change is complimented by changes in the button icons. If we want to ditch the promote/demote terminology, perhaps we can go with something like "bring forward" and "push backward".

Testing locally in both release and debug configuration on Mac catalyst worked fine for me 👌
