[lldb] Part 2 of 2 - Refactor `CommandObject::DoExecute(...)` to return `void` instead of ~~`bool`~~ Justifications: - The code doesn't ultimately apply the `true`/`false` return values. - The methods already pass around a `CommandReturnObject`, typically with a `result` parameter. - Each command return object already contains: - A more precise status - The error code(s) that apply to that status Part 1 refactors the `CommandObject::Execute(...)` method. - See [https://github.com/llvm/llvm-project/pull/69989](https://github.com/llvm/llvm-project/pull/69989) rdar://117378957
