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.

+    - the function principle of the windows clipboard:
+      a data provider offers all formats he can deliver on the clipboard
+      a clipboard client ask for the available formats on the clipboard
+      and decides if there is a format he can use
+      if there is one, he requests the data in this format
+
+    - This class inherits from IDataObject and so can be placed on the
+      OleClipboard. The class wraps a transferable object which is the
+      original DataSource
+    - DataFlavors offered by this transferable will be translated into
+      appropriate clipboard formats
+    - if the transferable contains text data always text and unicodetext
+      will be offered or vice versa
+    - text data will be automatically converted between text and unicode text
+    - although the transferable may support text in different charsets
+      (codepages) only text in one codepage can be offered by the clipboard
