Revert of nanobench: lazily decode bitmaps from SKPs (patchset #1 id:1 of https://codereview.chromium.org/572933006/)

Reason for revert:
skia:2944

Original issue's description:
> nanobench: lazily decode bitmaps from SKPs
>
> This makes it considerably cheaper to run SKP recording benchmarks, without
> affecting their measurements and without really affecting SKP playback
> benchmarks at all.
>
> On my machine, running out/Release/nanobench --match skp --config nondrendering
> drops in run time from 6.7s to 2.5s, and the peak RAM usage drops from 129M to 50M.
>
> I'm strongly considering making this lazy decoding the default.
