QmlDesigner: Add contains functions

After extensive
benchmarking(https://quick-bench.com/q/ajHEd5ZE-zmI2FoLQLGX9NREgmw)
there was a clear result that a forced inline variatic function provides
the fastest result.

static bool search(QByteArrayView input)
{
    return CoreUtils::contains(input,
                               "children",
                               "data",
                               "childrenRect",
                               "icon",
                               "left",
                               "transform",
                               "visibleChildren");
}
