WIN move dtrans code into vcl/win/dtrans

There is nothing abstract about either the clipboard or data
transfer code in that directory and it's just used on Windows.

All other backends implement this code in VCL, so this moves
almost all code, except for the common MimeContentTypeFactory,
into the vcl Windows backend / vclplug_win.

This also drops four DLLs: sysdtrans, dnd, dtrans and ftransl.
