[stable] Backports (#8449)

Browse Source 
* Use forked app_dirs crate for reverted Windows dir behavior  (#8438)

* Remove unused appdirs dependency in CLI

* Use forked app_dirs crate for reverted Windows dir behavior

* remove Tendermint extra_info due to seal inconsistencies (#8367)

* Improve VM executor stack size estimation rules (#8439)

* Improve VM executor stack size estimation rules

* typo: docs add "(Debug build)" comment

* Fix an off by one typo and set minimal stack size

This avoids the case if `depth_threshold == max_depth`. Usually setting stack size to zero will just rebound it to
platform minimal stack size, but we set it here just in case.

* Use saturating_sub to avoid potential overflow

* Upgrade crossbeam to 0.3
