Bug: https://github.com/flutter/flutter/issues/73392

Fix DropdownButton crash when viewport size is too small for the entirety of the menu's height (#76764)

5c14c528c [Windows] Hide Win32 API of the keyboard system behind ifdef (flutter/engine#24677) (#76931)

This reverts commit f8cd24de in an attempt to re-land it.

There are no changes in this PR from #74373, since it only failed Google internal tests, and we think that the solution involves updating those tests instead of changing this code.
