Enable ChromeFrame net tests for IE versions 8 and below. Changes include the following:-

1. Get rid of the dummy AtlModule registration in the chrome frame net test suite. This is no longer needed
   as there is an Atlmodule instance instantiated by the content code.

2. The TestSuite and NetTestSuite classes now provide special protected constructors which allow
   test instances to control whether an AtExitManager instance is created for the duration of the
   test. The ChromeFrame net test suite reuses the AtExitManager instance created in BrowserMain.

Fixes bug http://code.google.com/p/chromium/issues/detail?id=105435

BUG=105435
TEST=ChromeFrame net tests should now run on the builders.
