This reverts commit e64c72b9.

Reason for revert: This causes the https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Mac10.12%20Tests bot to turn red with webkit_layout_tests failures that are empty.

Original change's description:
> Stop running webkit_layout_tests on mac 10.12 and 10.13 w/ GPUs.
>
> And disable http/tests/media/video-load-metadata-decode-error.html,
> which appears to have a dependency on GPUs.
>
