Interactivity API: Use Script Modules data filter

[sirreal]

https://core.trac.wordpress.org/changeset/58579 introduced an API for passing data to Script Modules similar to what Interactivity API does.

Instead of its own implementation, change the Interactivity API to use the Core API via the script_module_data_{$module_id} filter.

Todo:

• All of the print/encode tests can be removed (that testing is now part of Script Modules: Add server to client data passing #6682).
• Add tests on the filter being used correctly.

✅ This will not work until client scripts are updated. The @wordpress/interactivity Script Module was updated in WordPress/gutenberg#61658 to try to get client data from an updated element ID. This requires @wordpress/interactivity@>5.7.0.

@luisherranz @cbravobernal @DAreRodz I'd love to get an Interactivity API review of this 🙏

Looks good to me 🙂

Good trick to update the JS handle beforehand 😄
