Add support for <action>/<parameters> XML format in ToolCallParser

- Added new pattern to parse <tool><action>...</action><parameters>...</parameters></tool>
- Handles both JSON and XML-style key-value pairs in parameters
- Example:
  <tool>
  <action>search</action>
  <parameters>
    <query>Apple AAPL Q4 financials Net Income Revenue</query>
  </parameters>
  </tool>
