fixed the bug of EmfMetricLoggingPublisher not properly publishing Long metrics

[Fred1155]

Motivation and Context

Customer reported that the Long metric cannot be published in EmfMetricLoggingPublisher because the original implementation directly cast the Long to Integer, which will result in an error.

Modifications

Changed the MetricEmfConverter class to write Long value using JsonWriter.writeValue(Long) method.

Testing

Added unit test case
