`knn` queries can have filter queries. Those filters may contain semantic queries (e.g. `knn`, `sparse_vector`, or `match` queries targetting `semantic_text` fields). We also need to intercept those in order to perform inference for their `query` field during the coordinator node rewrite. This commit achieves this with the following changes: - `SemanticKnnVectorQueryRewriteInterceptor` attempts to rewrite filter queries. This means we rely on a rewrite cycle to attempt to intercept every query down the tree of each filter query. - `InterceptedInferenceQueryBuilder` now has a `customCoordinatorNodeRewrite` method that subclasses can implement to implement additional rewriting logic needed, e.g. rewrite inner queries. - `InterceptedInferenceKnnVectorQueryBuilder` implements `customCoordinatorNodeRewrite` so that the filter queries are rewritten. This commit fixes the exceptions throws in elastic#138410. However, searches that contain semantic text queries as filters to a semantic text knn query will return `0` hits due to another issue that is captured in elastic#138184. Closes elastic#138410
