manifest_xml: initial support for <superproject>

At most one superproject may be specified. It will be used
to specify the URL of superproject.

It would have 3 attributes: remote, name, and default.
Only "name" is required while the others have reasonable defaults.

<remote name="superproject-url" review="<url>" />
<superproject remote="superproject-url" name="platform/superproject"/>

TODO: This CL only implements the parsing logic and further work
will be in followup CLs.

Tested the code with the following commands.

$ ./run_tests tests/test_manifest_xml.py
$ ./run_tests -v
