Revert of Make webkit_modules a split static library in non-component builds. (patchset #2 id:20001 of https://codereview.chromium.org/2145253003/ )

Reason for revert:
I suspect that this change can cause failure in the generate_build_files step on Windows.

Making a speculative revert to see if the issue is resolved.

Original issue's description:
> Make webkit_modules a split static library in non-component builds.
>
> Previously this was force to a source set because it was too large for official Windows builds to handle as a static library.
>
> This uses the split_static_library template for non-component official Windows builds so it can be a static library now.
