252f1cde - [lldb][test] Remove vendored packages `unittest2` and `progress` (#82670)

[lldb][test] Remove vendored packages `unittest2` and `progress` (#82670) The `unittest2` package is unused since 5b386158aacac4b41126983a5379d36ed413d0ea. The `progress` package was only used internally by `unittest2`, so it can be deleted as well.
