Add dawn version hash to cache keys.

Motivation is to simplify cache evicting by reusing the LRU to evict stale entries from older Dawn versions since there isn't already a simple cache busting solution. The dawn version will just be pushed into the cache keys instead so old version entries will eventually be retired.

- Removes the fingerprint from the GetCachingInterface API on DawnNative.
- Adds the "fingerprint", which was just the hash, to the device;s cache key directly instead.
