Reland "SkSurface asynchronous read APIs allow client to extend pixel lifetime"

This is a reland of ce240cc6fd8ec95bd051c7df2173dad2ae8f6ad6

Original change's description:
> SkSurface asynchronous read APIs allow client to extend pixel lifetime
> 
> Previously the pixel data passed to the client was only valid during
> the client's callback. This meant if the client wanted to defer
> processing of the data a copy was necessary.
> 
> Now we pass an object to the callback and the pixel lifetime is tied
> to the lifetime of that object.
> 
> The object may be holding a GPU transfer buffer mapped. We don't assume
> that the object will be released on the direct GrContext thread. So
> when the object is destroyed it posts a message to a new type,
> GrClientMappedBufferManager, hanging off the direct context. The direct
> context will periodically check for messages and unmap and then unref
> buffers so that they can be reused. Currently this is done in
> GrContext::performDeferredCleanup() and GrDrawingManager::flush().
> 
> The old API is kept around for backwards compatibility but it is
> reimplemented as a bridge on top of the new mechanism.
> 
> Also a utility function to SkImageInfo is added to directly make a new
> info with a specified dimensions rather than passing the width and
> height separately to makeWH().
