ES|QL: automatic prefiltering for semantic_text match queries

tracked in https://github.com/elastic/elasticsearch/issues/123043


When using match with semantic_text fields that are backed by dense_vector embeddings, we should automatically apply pre-filters similarly to what we do for knn https://github.com/elastic/elasticsearch/pull/131004.

The fact that we don't apply pre-filters right now constitutes a bug.
