  Log Message:
  -----------
  [analyzer] Add time-trace scopes for high-level analyzer steps (#125508)

Specifically, add a scope for 
- each work-list step,
- each entry point,
- each checker run within a step, and
- bug-suppression phase at the end of the analysis of an entry-point.

These scopes add no perceptible run-time overhead when time-tracing is
disabled. You can enable it and generate a time trace using the
`-ftime-trace=file.json` option.
