[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] Remove macRoman translation of keyboard keyValue in Win32 VM (#401)

There is code that transforms the presumably latin-1 key value into approximately MacRoman encoding in platforms/win32/vm/sqWin32Window.c
I let the archeologists debate if this code dates from Jurassic period or more distant paleozoic era, all I know is that we pay for what we don't buy...

Thus I propose to entirely remove that piece of code and disentangle a bit the spaghetti keyboard handling.

We indeed do not need this extra level of complexity anymore, images do not use macRoman encoding for a long time

On the contrary, images have to undo the translation by sending `macToSqueak` message in various subclasses of `KeyboardInputInterpreter`.

For the transition period, old images running on new VMs, or new images running on old VMs, might encounter a few hickups while interpreting non ASCII characters in case of exotic `KeyboardInputInterpreter`. That won't be the case of main `UTF32InputInterpreter` since it mostly uses the utf32 code passed through `eventBuffer sixth` position rather than keyValue passed thru `eventBuffer third`, except for some CTRL+key for which the keyValue is more-than-often < 128, and thus unaffcted by the proposed change.
