Move IndexedDB files out of in_process_webkit

Move IndexedDB files out of in_process_webkit

The browser-process implementation of IndexedDB was moved off the
WebKit thread in r208544; since that change has stuck, move the files
to their new home.

jam@ - can you take a look?

File content/browser/indexed_db/indexed_db_database.cc (left):

https://codereview.chromium.org/17840006/diff/1/content/browser/indexed_db/in...
content/browser/indexed_db/indexed_db_database.cc:1599:
DCHECK(!BrowserThread::CurrentlyOn(BrowserThread::WEBKIT_DEPRECATED));
This DCHECK actually landed in parallel with the thread move (it was previously
a TODO). It's now a bogus check since the IDB code is never on the WEBKIT
thread. Restore it to a TODO.

content/browser/indexed_db/indexed_db_database.cc:1810:
!BrowserThread::CurrentlyOn(BrowserThread::WEBKIT_DEPRECATED));
Ditto.
