Revert of Idle cleanup for worker context (patchset #5 id:200001 of https://codereview.chromium.org/2353033003/ )

Reason for revert:
This appears to be breaking some number of unittests - need to investigate further.

Original issue's description:
> Idle cleanup for worker context
>
> Currently, Skia flushes unused items out of its caches after ~1 second
> of non-use (50 flushes). This works fine while Skia is in-use, but when
> a worker context goes idle we stop calling into Skia altogether. This
> means that Skia will never flush out unused cache items from the last
> piece of work it did. This can lead to some rather large temporaries
> being kept around (~20mb).
>
> This change adds an idle cleanup process which flushes Skia's caches
> and cleans up worker context resources after a worker context is idle
> for 1 second.
