Make CFX_XMLParser less permissive
Currently the parser will accept arbitrary garbage before the first
element begins. This is causing issues with ClusterFuzz since it
generates a lot of trash inputs which take a long time to parse
inspite of being invalid.
This CL adds in a check of how deep the parse is when dealing with
text, and if it is at the top level scope, then only accept the
beginning of the root node.
