Reland of r114615: "chrome.clear: Increasing granularity of public API"

http://codereview.chromium.org/7717023 added more granular options to
BrowsingDataRemover. This CL exposes those options to the chrome.clear
extension API. Among other things, this means that chrome.clear.cookies()
will _only_ clear cookies, not cookies and site data.

At the moment, clearing any quota managed data type will clear them all.
That is being addressed in http://codereview.chromium.org/7839029/
but is independent from changing the public interface.

BUG=94334
TEST=browser_tests

Rubberstamp, LGTM. Looks like the compile error should be fixed.
