[lldb-dap] Improving consistency of tests by removing concurrency. (#165496) We currently use a background thread to read the DAP output. This means the test thread and the background thread can race at times and we may have inconsistent timing due to these races. To improve the consistency I've removed the reader thread and instead switched to using the `selectors` module that wraps `select` in a platform independent way.
