Prepare security bullets for Android: add issuer and change connection details.

This is the first of a series of CLs to expose the GetSecurityStyle()
explanations (currently only used in the DevTools Security panel overview,
untranslated) in the Android connection info popup (translated). It does two
things:

- Mention the issuer in the certificate bullet (for feature parity with the old
  Android connection info popup).
- Swap TLS connection settings values with their descriptions to avoid phrase
  substitution within a clause (for straightforward translation).

The relevant strings retain `translateable="false"` until a future CL, due to
non-trivial runtime logic about when to translate the strings.

BUG=587255, 657299
TEST=Open the DevTools Security panel, visit https://google.com, and verify that there is a green bullet stating "The connection to this site is using a valid, trusted server certificate issued by Google Internet Authority G2."
