Add throttle to TronChainAdapter

[coderabbitai]

Description

Add throttling functionality to the TronChainAdapter to control the rate of requests and prevent potential rate limiting issues.

Context

This follow-up action was requested during the review of PR #11531, which addressed transaction parsing fixes for the Tron chain adapter.

Implementation Considerations

• Implement request throttling mechanism in packages/chain-adapters/src/tron/TronChainAdapter.ts
• Consider configurable throttle limits
• Ensure throttling doesn't negatively impact user experience for normal transaction flows
