Export formatContainerProcessor for public API use (#3238)

Export formatContainerProcessor from roosterjs-content-model-dom public API
to enable users to use it in processorOverride for custom DOM-to-Model processing.
This allows customization of format container elements (e.g., blockquote) processing
without relying on internal module paths.
