support direct writing to top layer, and hide getTopLayer()

this should remove many of the chrome callers that today call
accessBitmap on the toplayer, so they can read/write those pixels.

The ultimate fix will be to support custom allocation of raster layers
(via GDI/cairo/mac) so we can remove PlatformDevice subclassing in
skia/ext
