Make NtpTrustedTime safer / expand docs
This commit makes a number of changes:
1) Documents / enforces thread safety, removes or deprecates unsafe
check-then-do methods / adds a way to get the NTP query result
atomically.
2) Delays configuration lookup until point of use: the config can change
due to various possible config overlays, e.g. MCC-based config.
(1) is because the threading model is currently unclear / possibly
unsafe - it looks like NtpTrustedTime is supposed to be single threaded
but it's also a singleton so could be accessed from multiple threads.
If NtpTrustedTime were not a singleton things might be easier but the
@UnsupportedAppUsage makes it difficult to change now.
(2) is to address the same issue as https://r.android.com/1182530,
contributed by Luca Stefani.
