[roll third_party/pigweed] pw_console: Early log message arrival fix

- The LogView class was not checking for existing messages in the
  LogStore instance on startup. This gave the impression that only one
  log arrived until the user scrolls or a new message arrives.
- Bump pw_console MAX_FPS to 30.
