Christoph Bergmeister bbd48f60e0 Add location history for Set-Location to enable 'cd -' scenario (issue #2188) (#5051)
* Implement location history feature for Set-Location.
This makes it possible to go back to the last directory using 'cd -',
which is exactly the same syntax as on Linux shells.

* Use an existing stack implementation instead of relying on an environment variable and move logic for 'cd -' into the internal class of SessionState.Path.SetLocation
Keep the (additional) setting of an environment for Unix system in case of mixed usage of cd and Set-Location to provide consistency.

* Use a bounded stack with a limit of 1000 and adapt tests.
Remove setting environment variable on Linux as discussed in PR.

* Fix test: use get-location explicitly to avoid subtle difference in the path string (e.g. an additional slash at the end)
Make syntax to .net call of environment consistent with surrounding code

* Move initialization of _workingLocationHistoryStack into constructor of SessionStateInternal and set the limit to 20 as discussed in PR 5051.

* Make new BoundedStack class in engine utils internal
