Make SkPaintFilterCanvas paints no longer COW.

The two existing external users of SkPaintFilterCanvas always end up
making a copy of the paint when the canvas is in use. As a result, the
extra overhead of doing COW is being wasted. In general, it seems easier
for users to optimize by simply not using the filter canvas when it
won't be making any changes. Also, no users are using the 'Type'.

After users are updated to this new API, the old onFilter can be
removed.
