Revert of Make GrResourceCache dynamically change between LRU and random replacement strategies. (patchset #8 id:140001 of https://codereview.chromium.org/2321563006/ )

Reason for revert:
Causing problems on Mac & Windows bots.

Original issue's description:
> Make GrResourceCache dynamically change between LRU and random replacement strategies.
>
> Random performs significantly better when each frame exceeds the budget by a small margin whereas LRU has worst case behavior.
>
> The decision of which to use is made based on the history from a few frames of the ratio of total unique key cache misses to unique key cache misses of resources purged in the last 2 frames.
