patch 9.1.0050: Win32 Keyboard handling is sub-optimal

Problem:  Win32 Keyboard handling is sub-optimal and has
          many issues with international keyboards
          (risa2000) (after v8.2.4807)
Solution: soft-rollback the change, allow the user to select
          a suitable key-translation strategy
          (Anton Sharonov)

Read about the details in the help:
    :h w32-experimental-keycode-trans-strategy

closes: #12752
