Revert of nanobench: lazily decode bitmaps in .skps. (patchset #1 id:1 of https://codereview.chromium.org/743613005/)

Reason for revert:
Some bots crashing.

Original issue's description:
> nanobench: lazily decode bitmaps in .skps.
>
> This cuts down on tool overhead when running something like recording only,
>     $ out/Release/nanobench --match skp --config nonrendering
> which doesn't usually ever need to decode the images.
>
> The actual measurements for recording don't change, as the decode is not in the timed section.  It just skips irrelevant code, removing it from the profile and making the tool run faster.
>
> This does, however, make a significant difference for playback speed.  Most skps draw faster with this patch, some slower.  I don't really have a good intuition for what's going on here.  There is a fixed clip acting as a viewport, so there are probably lots of images that don't ever need to be decoded.  Ideas?  Is this perhaps because we're now blitting from smaller, partially decoded source images?
