Reland PerformanceOverlayLayer golden test (#8140)
This reverts commit f1f19bba8f0089490962316867bd222727510ac5.

Now we shouldn't break the engine build as https://chromium-review.googlesource.com/c/chromium/tools/build/+/1480746 is landed. The golden test is disabled by default and we'll enable it later in our recipe and test it in presubmit tests.
