Clean up/fix DLL.h
* Change DLL_EXPORT to libqpdf_EXPORTS (internal to the build). The
new name is cmake's default, is more conventional, and is less
likely to clash with other symbols.
* Add QPDF_DLL_PRIVATE for non-Windows
* Make logic around when to define QPDF_DLL et al more explicit
* Add detailed comments
