AAPT2: Add support to strip namespaces from XML

The --no-xml-namespaces flag will strip namespace information from
compiled binary XML files in res/* (excluding res/raw/*) and
AndroidManifest.xml. It will also strip URI information from compiled
binary XML files in res/* (excluding res/raw/* and AndroidManifest.xml).

AndroidManifest.xml URI information is retained due to PackageParser, which
requires the Android URI for intent filters.
