Update Page Info on iOS to an interim Material Design state.

This brings it mostly in sync with other platforms by replacing two sections (identity info and connection info) with a single section containing a security summary and a sentence with details about what the security state means.

This CL also:
- Drops logic to show error strings related to and SHA-1 deprecation, since we don't detail this on desktop and some of these states can't even be detected on WKWebView anymore.
- Preserves the layout code for multiple sections, even if we only show a single one now.
- Preserves certificate information for devs/power users, since there is no other way to get the info until we have a certificate viewer on iOS (crbug.com/502470).
