Move AppWindowGeometryCacheTest to extensions_unittests

It was running in Chrome's unit_tests for historical reasons.

* Remove usage of Chrome's TestExtensionPrefs by instantiating our own
  simplified ExtensionPrefs.
* Move ShellAppSorting to NullAppSorting so it can be used for the above
  as well as app_shell.

BUG=397164
TEST=extensions_unittests
