Avoid polymorphic dispatch over JNI
When linked statically on GraalVM, JNI symbols declared in the overloaded form cannot be resolved. Luckily, all of `Native`'s callsites are in `Pointer` or itself, and all `native` methods of `Native` are non-public. This PR adjusts the JNA C API to avoid using overloaded `read`, `write`, or `getDirectByteBuffer`. Callsites are amended in `Pointer` accordingly.
