This adds an introductory message to try to inform users on how the debug console works and adds a little more information on the current target/process, similiar to the lldb driver. Here is an example of the introduction: ``` To get started with the debug console try "<variable>", "<lldb-cmd>" or "help [<lldb-cmd>]". For more information visit https://lldb.llvm.org/use/lldbdap.html#debug-console. Executable binary set to 'a.out' (arm64-apple-macosx15.0.0). Attached to process 1234. ```
