Issue Type: Enhancement

The jsontoxml function saves an intermediate copy of the xml representation. We should
also have the ability to stream process the resulting xml to avoid the intermediate copy.

Steven Hawkins resolved TEIID-2092.
-----------------------------------
Resolution: Done
took the approach of narrowly looking for the usage of jsontoxml (and xmlparse) as a
parameter to xmltable/xmlquery and ensured that stream handling was used instead.
the json streaming is a little convoluted since we are using the json ContentHandler as an
XMLEventReader, which needs converted to an XMLStreamReader, which needs wrapped by a
Saxon PullEventSource
updated the jsontoxml logic to set the xsi:type for non-string data
updated the xpathvalue function to accept a blob and corrected the xpathvalue parameter
