superproject: pass groups to ToXml method.

Added the following methods to XmlManifest class.
+ GetDefaultGroupsStr() - return 'default,platform-' + platform.system().lower()
+ GetGroupsStr() - Same as gitc_utils.py's _manifest_groups func.

+ Replaced gitc_utils.py's_manifest_groups calls with GetGroupsStr.
+ Used the above methods to get groups in command.py::GetProjects
  and part of init.py.

TODO: clean up these funcs to take structured group data more instead
      of passing strings around everywhere that need parsing.

Tested the code with the following commands.

$ ./run_tests -v

Tested the sync code by using repo_dev alias and pointing to this CL
and verified prebuilts/fullsdk-linux directory has all the folders.

Tested repo init and repo sync with --use-superproject and without
--use-superproject argument.

$ repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b androidx-main  --partial-clone --clone-filter=blob:limit=10M --repo-rev=main --use-superproject

$ repo_dev sync -c -j32
