Fix handling of cursor position reports in passthrough mode (#13109)

## Summary of the Pull Request

When the conpty passthrough mode is enabled, it often needs to send `DSR-CPR` queries (cursor position reports) to the client terminal to obtain the current cursor position. However, the code that originally handled the responses to these queries got broken by the refactoring of the `ConGetSet` API. This PR is an attempt to correct that regression.

## References

The conpty passthrough mode was introduced in PR #11264.
The refactoring that broke the cursor position handling was in PR #12703.

## Detailed Description of the Pull Request / Additional comments

Prior to the `ConGetSet` refactoring, the code that handled `DSR-CPR` responses (`InteractDispatch::MoveCursor`) would pass the cursor position to `ConGetSet::SetCursorPosition`, which in turn would forward it to the `SetConsoleCursorPositionImpl` API, and from there to the `VtIo` class.

After the refactor, all of those intermediate steps were removed - the cursor was simply updated directly in `InteractDispatch::MoveCursor`, and the `VtIo` call was moved from `SetConsoleCursorPositionImpl` to `InteractDispatch` (since that was the only place it was actually required).

However, when the conpty passthrough mode was introduced - which happened in parallel - it relied on the `SetConsoleCursorPositionImpl` API being called from `InteractDispatch` in order to handle its own `DSR-CPR` responses, and that's why things stopped working when the two PRs merged.

So what I've done now is made `InteractDispatch::MoveCursor` method call `SetConsoleCursorPositionImpl` again (although without the intermediate `ConGetSet` overhead), and moved the `VtIo::SetCursorPosition` call back into `SetConsoleCursorPositionImpl`.

This is not ideal, and there are still a bunch of problems with the `DSR-CPR` handling in passthrough mode, but it's at least as good as it was before.

## Validation Steps Performed

I've just manually tested various shells with passthrough mode enabled, and confirmed that they're working better now. There are still issues, but nothing that wasn't already a problem in the initial implementation, at least as far as I can tell.
