Fix for custom tools not being called by the agent

This PR fixes issue #2664 where custom tools are not being called by the crewAI agent in version 0.114.0, although they worked fine in version 0.108.0.

Root Cause

The issue was caused by changes to the ToolUsage class where the original_tools parameter was removed from the init method, but it's still being passed in the CrewAgentExecutor._execute_tool_and_check_finality method. Additionally, the way tools are selected has changed, with the original_tool variable being replaced with available_tool.

Solution

1. Added back the original_tools parameter to the ToolUsage.init method
2. Updated the _use method to check for original tools before falling back to available tools
3. Added a test case that verifies custom tool invocation works correctly

Testing

Created a new test that validates custom tool invocation and ran the existing test suite to ensure no regressions.
