Make auto_gen_test_config available to Bazel.
In the Bazel rule, the actual AndroidManifest.xml file isn't available
in the providers of the android_binary dependency. And for good reason,
we should also rely on aapt2 to dump the manifest contents from the
final packaged APK anyway, but this auto gen script doesn't support
reading the output of aapt2 dump.
This CL adds a simple reader of the output of `aapt2 dump xmltree`, and
enabled if the xmltree content is passed to this tool instead of
AndroidManifest.xml.
Also fixup auto_gen_test_config_test.py. The test was completely failing.
Test: atest auto_gen_test_config_test
Test: presubmits
