Call directly into ShowCertificateViewer from siteInfo UI
Call directly into ShowCertificateViewer from siteInfo UI

Previously, Brave took an indirection through DevTools, but this path
was removed in a refactoring [1]. This patch takes the strategy
of Chromium in calling more directly into the code to open this window,
e.g., see src/chrome/browser/ui/views/page_info/page_info_bubble_view.cc
