feat: picker max suggestions

[scomea]

📖 Description

While building a picker based ui with larger collections of suggestions I found that I needed to truncate the number of suggestions rendered in the UI "as you type". Makes sense for picker to enables this internally. This change adds a "max-suggestions" attribute to picker as well as showing a "type for more" message when large suggestion sets are truncated.

Also fixed an issue where max selection could be exceeded programmatically.

@scomea circling back to this, is it still needed?

I'm going to close this as we are avoiding features while we reconcile open PRs with #6951.
