Revert 232547 "Pepper: Move FileIO host from renderer to browser."

This change is being reverted due to some problems seen in integration testing.
See http://crbug.com/314884 for test failure details.

> Pepper: Move FileIO host from renderer to browser.
> 
> This change is large because it moves QuotaFileIO and PepperFileIOHost all at
> once to the browser process. Some code in the refactored PepperFileIOHost is
> moved from what's provided in FileAPIMessageFilter.
> 
> Tested locally with Bastion, From Dust, and Angry Bots.
