        [Qt] Redesign the build system
        https://bugs.webkit.org/show_bug.cgi?id=51339

        Part 1.

        Introduce CodeGenerators.pri and add common includepaths to WebCore.pri,
        thus unnecessary duplications can be removed from project files.

        No new tests needed.

        * CodeGenerators.pri: Copied from Source/WebCore/WebCore.pri.
        Don't add non-source generated files to SOURCES.
        * DerivedSources.pro: Change WebCore.pri to CodeGenerators.pri.
        * WebCore.pri: Move code generation rules to CodeGenerators.pri.
        * WebCore.pro: Move common options to WebCore.pri.
