b/372559388 This PR configures jni_generator for cobalt_apk_java. It creates the corresponding native class StarboardBridge for cobalt/android/apk/app/src/main/java/dev/cobalt/coat/StarboardBridge.java, adhering to Chromium's JNI standards. The StarboardBridge native class is implemented as a singleton and is initialized with the same JNIEnv and jobject used when calling the Starboard custom JniEnvExt::Initialize function. Additionally, it updates the JNI function calls in starboard/android/shared/application_android.cc to align with Chromium's modern JNI standards. This PR amends the reverted PR #4545 There was an issue in the reverted PR that there are old annotations @UsedByNative embeded in the inner function calls in getResourceOverlay, somehow making the app not able to launch.. Culprit -> https://github.com/youtube/cobalt/pull/4545/files#diff-22285847addbd15025f71dadd357129f86573e042655067048f94fae301fb1d3R480. We can not blindly replace @UsedByNative with @CalledByNative, when switching to @CalledByNative, we should make sure to replace all occurrence of @UserByNative inside, and implement the new JNI template functions. I don't get why compiler didn't complain about the getResourceOverlay issue tho.
