Pass JavaRef to Java methods in android_webview.

Pass JavaRef to Java methods in android_webview.

Update code in android_webview to use JavaRef when calling Java methods
via JNI, instead of passing bare jobject. Various function parameter
types are converted from jobject to JavaRef to enable calls to obj()
higher up the call chain to be removed.

Followup to https://codereview.chromium.org/2237943002/ where I removed all the
.obj() calls that could be removed mechanically. This fixes the remaining places
where we pass jobject to Java methods in android_webview.
