New positioning model: support for inset rectangle shape-outside

Update inset-rectangle tests to work with new positioning model.
Removed some test cases that aren't really needed or aren't applicable
with the new model. These test cases live in the CSS WG's repo now, so
they've been imported here.

This is a port from webkit of http://trac.webkit.org/changeset/153362
