[WPEX-1977] Experiment with a carousel block

[jrtashjian]

This experimental branch adds a dedicated carousel block which can be wrapped around any blocks, making each innerBlock a "slide" within the carousel.

The concept is possible though we are running into problems that prevent a good experience for users interacting with the block in the block editor. The idea is to replace each block within CoBlocks that includes carousel functionality to utilize this new block instead. This will consolidate logic for ease of maintainability and unify the features provided by the carousel.

This is a work-in-progress PR. It's put on pause for now with the intent to come back at a later date once/if we resolve the interaction issues.
