This is mostly s/public SkNoncopyable/SkNoncopyable/g.
Two classes (SkDrawLooper::Context and SkPicture::OperationList) don't actually work with SkNoncopyable because they introduce a virtual destructor. I added SkNoncopyableVirtual to make them work as intended. Sort of questionable whether they really need to be noncopyable in the first place, but I guess it doesn't hurt to keep the behavior the same.

Before, gradients would only interpolate the linear portion of the
quadratic equation if there was no perspective. This updates them to
do so even in the case that there is perspective. The rearrangement
of math causes noise differences in the following gm tests:
gradients_no_texture_gpu
gradients_view_perspective_gpu
gradients_local_perspective_gpu
gradients_gpu
