Ink: Move polyline_processing_jni from geometry module to strokes module and rename to mesh_creation_jni

It was already moved to the strokes package in cl/716272805, but its directory wasn't changed at that time. Also, the previous naming pattern was inconsistent with other JNI objects - the Kotlin-side object that this connects with is called MeshCreation, so use the name mesh_creation_jni.
