Create a hash table from id<-->key in SkImageFilter::CacheImpl
There is memory leak in the SkImageFilter::Cache. There are two sources
of memory leak:
1. The cache filling up quickly.
2. A slow small leak that never stops.
This CL solves the first issue, which prevents the cache filling up quickly.
This CL creates a new hash table that index the
SkImageFilter::uniqueID to an array of keys, and with the existing
key<-->Value hash table, we can have SkImageFilters proactively
purge content derived cached content when destroyed.
