Add support for additional XML tool call format in ToolCallParser

- Added new pattern to parse <tool>name</tool><tool_call>JSON</tool_call> format
- Handles both closing tag (</tool_call>) and end-of-string as terminator
- Works with formats like:
  <tool>search</tool>
  <tool_call>
  {"query": "Apple AAPL Q4 financial report"}
  </tool_call>
