In preparation for exporting an XML proto format for UAM to consume, this change brings the XML DOM API more in line with other APIs that do not make the Namespace a separate node. Treating Namespace declarations as just properties of an Element node makes the implementation of algorithms much simpler, as the constraints that Namespace nodes have only one child are now built in and traversing to find Element nodes is much simpler. Also made a bunch of quality of life improvements, like formatting and comment style. Test: make aapt2_tests Change-Id: Ib97ff1c4252b7907e2cc1f13a448dc4ca3b809a4
