[chromium] Enable more of webkit_unit_tests in component builds
https://bugs.webkit.org/show_bug.cgi?id=109369

Patch by James Robinson <jamesr@chromium.org> on 2013-02-10
Reviewed by Darin Fisher.

Updates all webkit_unit_tests (except for LevelDBTest) to go through the Platform API instead of directly
calling into webkit_support so they work in component builds.
