[sdk-platform-java] fix: Modify existing mechanism of logging errors in gax-batching to avoid looped calls

Existing error reporting mechanism in gax-batching uses JUL (`java.util.logger`) to log the errors. This mechanism can lead to the looped calls between the Java client logging library and gax in a case users configure the `com.google.cloud.logging.LoggingHandler` to serve as one of the JUL handlers. In such a case a call to write a log via JUL will land into gax-batching code (via java-logging). If an error arise, the gax-batching will call JUL to write an error log which, in turn, will return the flow back to the same gax-batching code.
To avoid such situation before the first call the current JUL handlers should be enumerated to ensure they do not include `com.google.cloud.logging.LoggingHandler`. If the latter occurs in the list, the error message should be logged to STDERR.
