Output build times for each pip package built
Metadata
Current evaluation
Feature request to output per-package build times during charmcraft pack, since --no-binary builds can be very slow. Open 737 days with no labels, no comments, and no maintainer response. The --no-binary behavior is still active in the codebase.
Suggested action: needs triage
Reason: The issue has no labels, zero comments, and no maintainer interaction in 737 days, showing no sign of triage. However, the underlying problem remains relevant: charm_builder.py and the poetry plugin still use --no-binary=:all: (confirmed in current code), so per-package build timing would still help diagnose slow builds. It should be assessed and either scoped or deferred, not closed as stale.

Issue body
### What needs to get done
During/after packing, please output the time it took to build each package.
### Why it needs to get done
Since charmcraft packs with `--no-binary`, build times can be very long.
It would be very useful for charm authors to know which parts of their deps contribute to build time.
For example, we had no idea that it's `pydantic_core` that is the lengthy one and not `pydantic` itself.
Such knowledge could help us in deciding if we want to keep a dep or drop it.
For example, httpx takes a long time to build, so one might prefer using urllib instead.
This could be either in a tree format similar to pipdeptree, or a flat list like strace. Either works :)
```
