I tried just re-using CHROME_ANDROID_OFFICIAL_BUILD, but that also added
-DGOOGLE_CHROME_BUILD. Didn't go through all the instances, but looks like most
of them are harmless.

What's the problem with this? All the desktop chromes use official builds on the
perf waterfall (see crbug.com/271252). Why is this not possible for webview?
