robertphillips ed42059d2f Move offset and CTM from LayerCache Key to per-hoisted-layer info 
This CL reduces the amount of information used in the layer cache key:
- the stop value isn't needed since the start value uniquely identifies the layer in the picture.
- only the upper-left 2x2 portion of the CTM should be used as a key for looking up cached layers.
- individual layers can be redraw in different locations so the final offset cannot be a part of the key.

Since this data is no longer stored in the cached layer, but is still required to draw the cached layer, it is now stored in the per-layer information (i.e., HoistedLayer).

This is split out of (Fix sub-picture layer rendering bugs - https://codereview.chromium.org/597293002/).
