Support TransferableResource::is_software

When the GPU process fails to initialize, or when the --disable-gpu
switch is provided, the delegating renderer will transfer resource
mailboxes through shared memory pixel data instead of through shared
texture IDs in the GPU process.

Handle this by uploading the pixel data ourselves with
createTextureFromImage, also allowing us to render tiles in the
QtQuick 2D Renderer.
