Windows: workaround to make Windows Ink tablet API work

Now Wintab is not initialized when starting Blender with the tablet API
preference set to native, since that disables Windows Ink.

Note that changing the tablet API requires restarting Blender for changes
to take effect. This serves as a stopgap to allow use of Windows Ink until
runtime API switching is merged.
