Oilpan: switch ImageLoader to be prefinalized.
If an ImageLoader for an SVGImage ends up being swept out along with a
FrameView (a ScrollableArea), the former may circuitously end up accessing
the latter via its destructor. Having both be eagerly finalized, or
prefinalized, doesn't guarantee a correct destruction order.
Hence, to address, arrange for the ImageLoader to be finalized/disposed of
first by way of a prefinalizing action.
