Close #16474.

What this PR addresses

As described in the issue above, cargo build --timings and cargo report timings each had its own metric collection logic. Because cargo report timings will supersede cargo build --timings, this PR try to remove redundant logics from core/compiler/timings/mod.rs.

Review points

  • I'm not sure if it's appropriate to modify logger for refactoring. However, logs emitted inside core/compiler/timings/mod.rs alone is not enough for prepare_context_from_iter() to properly replay the build so I think this is an appropriate way.

I'm not sure if it's appropriate to modify logger for refactoring. However, logs emitted inside core/compiler/timings/mod.rs alone is not enough for prepare_context_from_iter() to properly replay the build so I think this is an appropriate way.

The overall direction looks reasonable to me!

Please see #16474 (comment), since they are already assigned to the parent issue, I have no objection to handing this PR over to @kurasaiteja (of course if they want).
