Bring the group tag back to VectorDrawable.
This is the first step, including:
1. Bring the group tag back by reverting.
2. If there is no group tag, then treat all the paths as a single group.
Make sure our test cases covering both cases.
At the same time, fix one tiny UI bug in the test.
TODO:
1. Move the rotation to the group tag.
2. Add translation/scale to the group tag.
3. Convert the group into a tree hierarchy.
