[CSS Shapes] Import and fix polygon shapes reftests

[CSS Shapes] Import and fix polygon shapes reftests

Import these polygon shapes reftests and fix them.
Note that these tests should be imported at some point.

This is based on http://trac.webkit.org/changeset/172973 by Zoltan Horvath <zoltan@webkit.org>;.

From the WebKit patch commit log:
We didn't respect the shape-margin before a positioned polygon, since we checked
the shape-margin for only 1 vertex for a polygon edge. This patch fixes the behavior,
removes the tests from the skipped list and updates 1 test, which was incorrect.

LGTM.

Can you also import the details from the description of the WebKit patch?
