bc604c7e - [lldb] Broadcast `eBroadcastBitStackChanged` when frame providers change (#171482)

[lldb] Broadcast `eBroadcastBitStackChanged` when frame providers change (#171482) We want to reload the call stack whenever the frame providers are updated. To do so, we now emit a `eBroadcastBitStackChanged` on all threads whenever any changes to the frame providers take place. I found this very useful while iterating on a frame provider in lldb-dap. So far, the new frame provider only took effect after continuing execution. Now the backtrace in VS-Code gets refreshed immediately upon running `target frame-provider add`.
