Revert of Default components to static libraries in GN build

Revert of Default components to static libraries in GN build (patchset #3 id:40001 of https://codereview.chromium.org/2060983002/ )

Reason for revert:
Build broken:
https://build.chromium.org/p/chromium.perf/builders/Win%20x64%20Builder

See https://bugs.chromium.org/p/chromium/issues/detail?id=619949
For recommendation to revert.

Original issue's description:
> Default components to static libraries in GN build
> 
> Previously components would be source sets in non-component mode. Some test targets link large components in chrome but use almost none of them, and including all object files makes these links very slow.
> 
> Reland of https://codereview.chromium.org/2043873004/ and https://codereview.chromium.org/2063483002 but disabled for official Windows builds.
> 
> In support of the official condition, is_official_build moved to BUILDCONFIG. Since this is really a different level of debug/release, this may actually make more sense. The documentation around this was enhanced a lot, official now automatically turns off debug, and it will assert if you override both to produce an official debug build.

Please don't revert, I can fix this easily another way. Reverting this will
cause a Windows try builder time exceed its SLA.

I agree, let's fix the builder instead.
