Refactored the policy code to avoid BrowserThread.

The policy code now mostly uses TaskRunners, so that it can move into a
component without DEPS layering violations. The remaining classes that use
BrowserThread directly are meant to stay in //chrome and instantiate the policy
system.

Also cleaned up some unused includes and unused arguments.
