Remove the SCT viewer UI
It is not implemented across all platforms and has a few rough polish
edges that are unlikely to get fixed. As part of the general work
towards simplifying the website settings UI, remove the SCT viewer.
Details about the SCTs are available via chrome://net-internals,
and will remain there until a more holistic view is provided by the
ongoing DevTools work
