Add hierarchy operations to container transaction
Also add a way to query for child containers of a container.
Combined, these provide enough flexibility to re-arrange
containers to system-ui. For now, it is locked-down a bit so
it only provides children of TaskTiles and can only reparent
ActivityStacks. Eventually, this can be expanded for nested
tasks or display areas.

Test: Added TaskTileTest#testHierarchyTransaction
