Reviewed by Tony Chang.

Source/WebCore:

Convert frontend callers to use the new backend createTransaction
call which is the final divorce between the frontend and backend
transaction objects. This allows an asynchronous call in Chromium
and allows the front and backend to have their own lifecycle,
allowing the backend to be cleaned up as soon as a transaction is complete,
rather than waiting for the JS object to get cleaned up.

No new tests, this is a refactor covered by existing tests.
