Make webkit_modules a split static library in non-component builds.
Previously this was forced 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.
Updates the split_static_library template to handle the case where an output name is specified.
