03896403 - [lldb-dap] Migrate attach to typed RequestHandler. (#137911)

[lldb-dap] Migrate attach to typed RequestHandler. (#137911) This updates the `attach` request to the typed `RequestHandler<protocol::AttachRequestArguments, protocol::AttachResponse>`. Added a few more overlapping configurations to `lldb_dap::protocol::Configuration` that are shared between launching and attaching. There may be some additional code we could clean-up that is no longer referenced now that this has migrated to use well defined types.
