Loïc Sharma 649b38752e [Embedder] Refactor how semantic updates are mapped (flutter/engine#44553) ...

This refactors how engine semantic updates are mapped to embedder semantic updates. There are no behavioral changes.

Part of https://github.com/flutter/flutter/issues/119970, https://github.com/flutter/flutter/issues/98948

Next PR: https://github.com/flutter/engine/pull/44616

## Background
For https://github.com/flutter/flutter/issues/119970, we will need to update the embedder API to add string attributes to semantic nodes' text values. There are multiple kinds of string attributes, and each text value can have multiple string attributes. This requires gnarly mapping code that's best kept out of `embedder.cc`.
