Revert of Precompile more in Blink in Windows for faster compilations (patchset #1 id:1 of https://codereview.chromium.org/1227953008/)
Reason for revert:
A chromium build bot broke with bad headers again. (see bug)
The pch file does not seem to be recompiled when it should be.
BUG=511945
Original issue's description:
> Precompile more in Blink in Windows for faster compilations
>
> One reason Blink is slow to compile is that there is a lot of code
> included in every compilation unit since everything depends on either
> LayoutObject.h or Document.h and those in turn include huge portions
> of the rest of Blink.
>
> By precompiling LayoutObject.h and Document.h the compilation of core and
> modules in Blink can be 4 times faster (4 minutes instead of
> 19 minutes on my computer).
>
> The downside is that it will introduce Document.h and LayoutObject.h
> also in compilation units that didn't expect it, for instance
> XPathGrammer.y that suddenly will have both blink::Path and
> blink::XPath::Path in scope (and blink::Filter / blink::XPath::Filter)
>
> Note that distributed compilation system disables precompiled headers
> globally so this will *not* make trybots faster.
>
> This is a new attempt at this change after bug 511945 scared us into
> reverting it. We still do not know the exact cause of 511945 but we
> are making another attempt with this.
