Description

In #652 we added support for JNI mode to generate a version script file for the linker to use in DCE. We should do the same for FFM, as it also generates some thunks.

Research direction

Start by reading issue #652 and its JNI version-script implementation, then trace jextract's FFM generation path and how it handles the thunks mentioned here. Done means FFM mode also emits a linker version script suitable for dead-code elimination, matching the JNI behavior.
