What's changed and what's your intention?

In this PR, we implement a macro gen_jni_sig that generates the jni signature from the java method signature. With this macro, we can avoid manually write the list of jni native and signature list when we register native method.

Besides, since we provide a register native function, in the java binding dynamic library, we don't have to export each jni method one by one. We change to provide a single method JNI_OnLoad, which will be called and register the jni method when the dynamic library is loaded.

LGTM! These macros are amazing! Maybe we can remove
the prefix Java_com_risingwave_java_binding_Binding_ so that we can have the same native method names in Rust.

Just had a look at the crate. It aims to convert the method name to a name that is able to automatically recognized by jvm when loading the dynamic library. However, in this PR, we have changed to register the native methods manually instead of via a predefined name mapping rule, and therefore it's unnecessary for us to maintain the method name according to the rule with the macro in the crate.
