Closes #30714 Bedrock converse api expect to see tool options if at least one tool was used in conversation in the past messages. Right now if `LanguageModelToolChoice::None` isn't supported edit agent [remove][1] tools from request. That point breaks Converse API of Bedrock. As was proposed in [the issue][2] we won't drop tool choose but instead will deny any of them if model will respond with a tool choose.
