Alternate bundler: use equivalent native plugins for built-in plugins

While we won’t use native plugins for equivalents of Next.js specific plugins, we should use these for equivalents of built-in plugins like `ProvidePlugin`, `IgnorePlugin`, and `EntryPlugin`. Otherwise, Rspack behaves unexpectedly.

Test Plan: Successfully build `@formbricks/web`
