CacheStorage: [Retry] Merge CacheStorageListener into CacheStorageDispatcherHost (1)

CacheStorage: [Retry] Merge CacheStorageListener into CacheStorageDispatcherHost (1)

Original: https://codereview.chromium.org/1101733005/

CacheStorageListener and CacheStorageDispatcher are now in a 1:1 relationship
and the indirection is no longer necessary. As a first step of merge, this CL
moves message handlers for CacheStorage API from the listener to the dispatcher.

Hi falken@, can you take a look at this?

(especially diff between the patchset1 and 2. The original one was reverted due
to my silly mistake...)

Thanks!
