ff0568f7 - [lldb] Fix memory monitor shutdown on Linux using eventfd (#178083)

[lldb] Fix memory monitor shutdown on Linux using eventfd (#178083) The current linux implementation has a 1 second timeout when polling for memory pressure. lldb-dap may take up to an extra 1 second to shutdown. Use an event file descriptor to immediately stop the memory monitor thread. Fixes #150220 (cherry picked from commit a5ffce0faebe5f49d8befb774f4cb781b9e33df7)
