Title: add antialias coverage for conformance/context/premultiplyalpha-test.html

wtu.create3DContext(...) will set antialias to false by default and can't catch errors occurred when antialias is true.

It is better to add antialias coverage to these test cases by setting antialias to true explicitly.
