Include search functionality for type search in local modules

[nipunayf]

Purpose

This PR updates the existing submodule type search to include a relevance-based sorting mechanism. Each search result is now assigned a relevance score that determines its display order.

Since the respective types are not indexed, there is no inverted index available to calculate the search rank. As an alternative, the relevance score is computed manually to mimic the ranking behavior of SQLite FTS search.

Fixes wso2/product-ballerina-integrator#1601

Relevance Score Calculation:

1. Exact Match (100pts): Assigns the highest possible score if the type name perfectly matches the query.
2. Prefix Match (50pts): Awards a high score if the type name starts with the query.
3. Substring Match (up to 10pts): If the query appears within the type name, it assigns a score that decreases as the match position moves further from the start.
4. Fuzzy Match (up to 5pts): As a fallback, it uses the Levenshtein distance to score based on similarity, tolerating typos.
5. Abbreviation Bonus (3pts): Adds points if the query matches the CamelCase initials of the type name (e.g., "HC" for "HttpClient").
6. Description Bonus (2-3pts): Adds extra points if the query is found in the type's description, with a higher bonus if it's at the beginning.

Pull Request Overview

This PR adds search functionality for types in local modules with a relevance-based scoring mechanism to improve search result ordering. The scoring system includes exact match, prefix match, substring match, fuzzy match, abbreviation matching, and description-based matching. Additionally, the PR updates dependency versions for HTTP and JSON data libraries, fixes primitive type handling in reference types, and includes test resources for validating the search functionality.

Key Changes

• Implemented relevance-based type search scoring for local module types
• Updated HTTP library version from 2.14.6 to 2.14.7
• Updated JSON data library version from 1.1.1 to 1.1.3
• Enhanced primitive type handling to support additional integer subtypes (Signed8/16/32, Unsigned8/16/32) and new types (byte, string:Char, regexp:RegExp)
