MinGW libstdc++ up to GCC 16 does not treat a reparse point as a link in std::filesystem::remove_all, so a host tree that holds a symlink is walked through the link and never returns. Add RemoveTree, which removes the tree itself on Windows, and use it where save data, app content and the shader disk cache removed host trees. The libstdc++ fix is in GCC 17 (88856ad855ae).
