Rajesh Thallam 6bc6d64a12 langchain_google_vertexai[patch]: Add support for SystemMessage for Gemini chat model (#15933)
- **Description:** In Google Vertex AI, Gemini Chat models currently
doesn't have a support for SystemMessage. This PR adds support for it
only if a user provides additional convert_system_message_to_human flag
during model initialization (in this case, SystemMessage would be
prepended to the first HumanMessage). **NOTE:** The implementation is
similar to #14824
