Implement WithFieldName interface for QueryBuilder implementations in plugins

[jainankitk]

What is the expected behavior?

For generating richer query shape information, QueryBuilder implementations within OpenSearch plugins should implement (if relevant) recently introduced WithFieldName interface. Some of the known QueryBuilder extensions with core:

    1 - k-NN
    1 - alerting
    1 - security-analytics
    3 - neural-search
    5 - opensearch-learning-to-rank-base

Probably, we can start by creating issue for each of these plugins if WithFieldName interface is relevant for those QueryBuilder implementations.
