I am of two minds about this.

On the one hand this is a rather sweeping change which may or may not have an
unpredictable impact on build times on the bots. It also means that all files
get all these defines, which could be seen as a downside, but that's already
happening anyway when precompiled headers are being used. However, it does mean
that we stop getting compile errors when something which needs to be included
isn't being included locally (though this is confusing as it means it built for
the developer but will fail on the bots). It seems like IWYU is supposed to take
care of that sort of thing though.

On the other hand, it means that the state of chromium_win_pch isn't changing
the include order. All the files are getting all of these defines consistently.
Also, it makes this change work.

I suppose one alternative to this is to just force include stdint.h to make sure
it always comes first. I'd have to figure out a good place to do that though...
precompile.gypi is already in a nice place to do this.
