commit df040f996f49df9c38adff7ef84f9d8afd572085
Author: Pritam <pritam.nikam@samsung.com>

CookiesFetcher cleanup.

Current implementation of CookiesFetcher keeps the application context as a
state information. That we can get that statically from the
ContextUtils#getApplicationContext(). In that case, we can simply get rid of
CookiesFetcher java and c++ implementation.

BUG= 816801
