feat(sdk-coin-cosmos): generic configuration driven test cases for sh…

[baltiyal]

This pull request introduces several enhancements to the Cosmos SDK module, focusing on adding test utilities, type definitions, and dependencies for streamlined testing and development. The most significant changes include the addition of utility functions for test data generation, comprehensive type definitions for test data structures, and updates to the package dependencies.

Additions to test utilities and type definitions:

• Test data generators: Introduced generateAddresses, generateTxIds, generateCoinAmounts, and other functions in test/testUtils/generators.ts to simplify the creation of test data for Cosmos SDK-based coins. These functions handle common test scenarios like generating addresses, transaction IDs, and coin amounts.
• Type definitions: Added test/testUtils/types.ts to define interfaces for test data structures, including ChainConfig, TestTransaction, TestAddresses, TestCoinAmounts, and others. These types ensure consistency and clarity in test data usage.

Updates to package dependencies:

• Dependencies and devDependencies: Updated package.json to include new dependencies like @bitgo/sdk-api, @cosmjs/encoding, and @bitgo/sdk-test, which are essential for Cosmos SDK functionality and testing.

Utility functions for test data management:

• Test data utilities: Added functions in test/testUtils/utils.ts for managing test data, such as getAvailableTestCoins, getTestData, and getAllTestData. These utilities streamline the loading and usage of test data across the test suite.

Simplified exports for test utilities:

• Centralized exports: Created test/testUtils/index.ts to re-export all test utility modules (types, generators, utils), providing a single entry point for accessing test utilities.
