Reland changes to enable worker layout tests. Compared to last review (http://codereview.chromium.org/50045), the following changes are made:

1) Add chrome/test/worker/DEPS to address checkdeps error.
2) Change test_expectations.txt to skip some worker layout tests.
3) Add test_worker.vcproj to webkit.sln so that test_worker.dll can be built for WebKit build.
