[Search Query Categorization] Extract field related information

[deshsidd]

This task is part of the Search Query Categorization Meta task and the Query Visibility Project.

We need to use Telemetry metrics framework to capture the number and types of input fields involved in the queries.

This will be useful for analysis and to get more visibility regarding the search queries.

Phase 1: #10250
