[Fix] CI/CD - Fix Bedrock tool calling test failures with non-serializable objects and internal parameters (#17930)

* fix(bedrock): filter non-serializable objects from request params

- Enhanced filter_exceptions_from_params() to filter callable objects (functions) and Logging objects
- Applied filtering in Bedrock's _prepare_request_params() before deepcopy
- Applied filtering to additional_request_params before JSON serialization
- Prevents TypeError during deepcopy (APIConnectionError objects) and JSON serialization (functions, Logging objects)
- Fixes test_bedrock_tool_calling test failures

Root cause: MCP-related functions (handle_chat_completion_with_mcp, completion_callable) and litellm_logging_obj were incorrectly added to optional_params via add_provider_specific_params_to_optional_params(), which then ended up in additional_request_params. These objects should be in litellm_params, not optional_params.

* fix(bedrock): filter internal MCP parameters from API requests

Filter out LiteLLM internal/MCP-related parameters (skip_mcp_handler,
mcp_handler_context, _skip_mcp_handler) from additional_request_params
before sending to Bedrock API to prevent 'extraneous key' errors.

- Added filter_internal_params() helper function in core_helpers.py
- Applied filtering in Bedrock's _prepare_request_params() method
- Fixes test_bedrock_completion.py::test_bedrock_tool_calling

* fix: mypy type error

* fix: add filter_exceptions_from_params to recursive function ignore list

- Add filter_exceptions_from_params to IGNORE_FUNCTIONS in recursive_detector.py
- Function is safe: has max_depth parameter (default 20) to prevent infinite recursion
