All JDK native libraries needs to have a proper `JNI_OnLoad`, set either by
`DEF_STATIC_JNI_OnLoad` or `DEF_JNI_OnLoad`. This is so that in a static build,
the JVM can recognize that the library is already loaded, and does not try to
load a (non-existent) external library.
Our bundled version of freetype is missing such a marker.
This turns out to be a problem just on Windows, since the
`System.loadLibrary("freetype")` code in `FontManagerNativeLibrary` is only
executed on Windows. However, the cost of including this in the bundled
versions on all platforms is very small, and it is a safeguard for any future
changes. In practice, freetype bundling is only enabled on Windows anyways.
