[beta] Backports (openethereum#8450)

* Use forked app_dirs crate for reverted Windows dir behavior  (openethereum#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 (openethereum#8367)

* handle queue import errors a bit more gracefully (openethereum#8385)

* Improve VM executor stack size estimation rules (openethereum#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
