Rollup merge of #137080 - jieyouxu:more-tracing, r=onur-ozkan
bootstrap: add more tracing to compiler/std/llvm flows
- Add more tracing to compiler/std/llvm flows.
- Two drive-by nits:
1. Take `TargetSelection` by-value for `builder.is_builder_target()`. Noticed while adding tracing; follow-up to #136767.
2. Coalesce enzyme build logic into one branch.
- Document `COMPILER{,_FOR}` tracing targets for #96176.
- No functional changes.
### Testing
You can play with the tracing locally with:
```
$ BOOTSTRAP_TRACING=bootstrap=debug ./x build library
$ BOOTSTRAP_TRACING=bootstrap=trace ./x build library
$ BOOTSTRAP_TRACING=bootstrap=trace,COMPILER=trace,COMPILER_FOR=trace ./x build library
```
### Previews
```
$ BOOTSTRAP_TRACING=bootstrap=debug ./x build library
```
```
$ BOOTSTRAP_TRACING=bootstrap=trace,COMPILER=trace,COMPILER_FOR=trace ./x build library
```
