PDF Viewer: Stop running remaining tests with the pre-PDFViewerUpdate UI.

 - Delete PDFExtensionTestWithParam class.
 - Update all subclasses to subclass PDFExtensionTest instead.
 - Update various tests that implement testing::WithParamInterface and
   no longer need to do so.

After this CL, there are no tests running with PDFViewerUpdate turned
off.
