Do not skip subtrees with wheel or touch handlers

Do not skip subtrees with wheel or touch handlers

When calculating draw properties, we attempt to skip subtrees whenever
we can, but we missed a corner case: even though we don't necessarily
draw a layer with a wheel or touch handler, it will participate in hit
testing and must therefore have up-to-date transforms, targets, etc.
In the same way that we've added logic to prevent skipping subtrees
containing layers with copy requests, this CL prevents skipping subtrees
with handlers.
