Enable substream slicers and Cartesian product slicers in connector builder

[sherifnada]

Both substream slicers and cartesian product slicers should be supported in the UI.

Acceptance criteria

• Substream slicer should be selectable from the list of slicing options
• Parent stream should select reference to another stream in the UI
• Circular dependencies should be caught
• Cartesian product slicers should be selectable from the list of slicing options
• Any slicers should be able to be added to the list of sub-slicers for cartesian product slicers

Implementation notes:

• add stable id to each stream in the builder values
• Use it to reference the parent stream
• before mapping to the manifest, check for cycles in the references - if there are some, set an additional error state and hide the stream test panel like if the listing call fails
• On building manifest, recursively inline stream definitions into each other

In review, however it's unclear how to handle some weird part about how substream slicers properties are managed on the CDK level.
