Export DxgiDuplicatorController when building as shared lib

This class is accessed by Electron for its desktop capture support,
but it breaks with component builds on Windows because the symbols
aren't exported by the dll.
No behavior change at runtime, only modifies the generated .lib
when building as a shared library (static builds are unchanged).
