SimpleChatTC:ToolCallErrPath:ToolTemp and MultiChatUIChatShow

Update the immidiate tool call triggering failure and tool call
response timeout paths to use the new ToolTemp and MultiChatUI
based chat show logics.

Actual tool call itself generating errors, is already handled
in the previous commit changes.
