[SBProgress][CLI] Configure sbprogress events to be emitted for the CLI (llvm#133309)

In the original SBProgress patch, llvm#123837, I didn't ensure the debugger
was broadcasting these events to the CLI as SBProgress has far been
focused on DAP. We had an internal ask to have SBProgress events
broadcasted to the CLI so this patch addresses that.
