feat(miniflare): add unsafeHandleDevRegistryUpdate callback option

[edmundhung]

Fixes n/a.

This PR adds a new option unsafeHandleDevRegistryUpdate to Miniflare that allows users to register a callback function that gets invoked whenever the dev registry is updated with changes to external services that the current worker depends on.

This will be used by Wrangler to update bindings tables in a later PR (#10245).
