feat: use the new onAssetsMarketData handler

Explanation

Current State and Problem

The MultichainAssetsRatesController currently uses the deprecated onAssetsConversion handler to fetch asset market data from Snaps. This handler interface is outdated and doesn't align with the current Snaps SDK architecture, which has evolved to provide better separation of concerns and more robust data handling.

Solution

This PR updates the MultichainAssetsRatesController to use the new onAssetsMarketData handler instead of onAssetsConversion. This change:

1. Improves handler interface: The new onAssetsMarketData handler provides a more standardized and reliable interface for fetching asset market data from Snaps
2. Aligns with current SDK: Updates the controller to work with the latest Snaps SDK architecture
3. Enhances maintainability: Uses the current best practices for Snaps integration

Dependency Updates

Alongside the main functional change, this PR also updates several Snaps-related dependencies across multiple packages to ensure compatibility and access to the latest features:

• @metamask/snaps-sdk: ^7.1.0 → ^8.1.0
• @metamask/snaps-utils: ^9.4.0 → ^10.1.0
• @metamask/snaps-controllers: ^12.3.1 → ^13.1.1

These updates are necessary because:

• The new onAssetsMarketData handler is available in the updated SDK versions
• The updated packages provide better performance and security improvements
• Maintaining consistency across the codebase with the latest Snaps ecosystem

Package-Specific Changes

The changes affect multiple packages because they all depend on the Snaps ecosystem. Each package's changelog has been updated to reflect the specific dependency changes that apply to it, ensuring transparency for consumers.

References

• Related to: Snaps SDK migration and handler interface improvements
• Consumer impact: This change improves the reliability of asset market data fetching but maintains backward compatibility for the public API
