fix(ai): fix renders for empty toolUse messages

[thaddmt]

Description of changes

• Developer can override the sendMessage utility to send messages with tools that are not renderable in the AIConversation component example below:
• Updates all of our response components to be prefixed with UI_ to be easier to tell as response component tool uses rather than regular tool uses
• Filters out messages that are not renderable, i.e only render empty tool use blocks

handleSendMessage={(content) =>
          sendMessage({
            ...content,
            toolConfiguration: {
              tools: {
                generateRecipe: {
                  description: "List ingredients needed for a recipe",
                  inputSchema: {
                    json: {
                      type: "object",
                      properties: {
                        ingredients: {
                          type: "array",
                          items: {
                            type: "object",
                            properties: {
                              ingredientName: { type: "string" },
                              quantity: { type: "number" },
                              unit: { type: "string" },
                            }
                          },
                        },
                      },
                    },
                  },
                },
              }
            }
          })
        }

This makes it so that we have to run this utility every time responseComponents changes, which responseComponents is set on the createAIConversation so it shouldnt be changing much if at all

[calebpollman]

Probably overkill and something i usually nitpick, but should we make this more specific by prefixing AMPLIFY_ as well?

[thaddmt]

Sure, happy to add

[calebpollman]

This will create a new reference on each render, regardless of whether responseComments changes. Tbh kind of surprised that the React linting rules aren't complaining

[thaddmt]

Yeah I guess I'm used to our linting rules complaining abou this if you send in an object like {foo, bar} so when this didn't complain i was a little unsure lol
