Remove circular module dependency

[rmunn]

Fix #814.

The build warnings ultimately came from the fact that $lib/forms/superforms.ts imports a single function from . (which in context is $lib/forms/index.ts), while at the same time $lib/forms/index.ts is importing and re-exporting everything, including the lexSuperForm function that's used all over our Svelte components.

There were three possible solutions:

1. Configure Rollup (via vite.config.ts) to use the manualChunks option, requiring us to make decisions about what goes in every chunk. Not worth the cost and effort at this point.
2. Change every place that imports lexSuperForm to import it from $lib/forms/superforms instead of from $lib/forms. This would have touched about a dozen files.
3. Change one single import in $lib/forms/superforms.ts to import from ./utils instead of from ., thereby eliminating the circular import situation. This touches only a single line in a single file, but it eliminates the issue.

Obviously, I went with option 3.

Nice fix. My personal opinion is that the comment should go.

I did not intend my last review to be a change request....even though it sort of is 😉

@myieye - Sure. Now that we're all aware of the issue, the comment has (mostly) served its purpose. Go ahead and re-review when you get into the office.
