This PR changes how we treat the launch sequence in lldb-dap. - Send the initialized event after we finish handling the initialize request, rather than after we finish attaching or launching. - Delay handling the launch and attach request until we have handled the configurationDone request. The latter is now largely a NO-OP and only exists to signal lldb-dap that it can handle the launch and attach requests. - Delay handling the initial threads requests until we have handled the launch or attach request. - Make all attaching and launching synchronous, including when we have attach or launch commands. This removes the need to synchronize between the request and event thread. Background: https://discourse.llvm.org/t/reliability-of-the-lldb-dap-tests/86125
