Move the PluginDataRemover class to content, and remove the chrome pieces from...

Move the PluginDataRemover class to content, and remove the chrome pieces from it. This class really belongs in content because it's part of the web platform. I've also wrapped it with an interface that is used by chrome.

BUG=98716
Review URL: http://codereview.chromium.org/8590016

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@110530 0039d316-1c4b-4281-b951-d872f2087c98
