Speedup environment activation, part 2 (#25633)
This is a direct followup to #13557 which caches additional attributes that were added in #24095 that are expensive to compute. I had to reopen #25556 in another PR to invalidate the GitLab CI cache, but see #25556 for prior discussion.
### Before
```console
$ time spack env activate .
real 2m13.037s
user 1m25.584s
sys 0m43.654s
$ time spack env view regenerate
==> Updating view at /Users/Adam/.spack/.spack-env/view
real 16m3.541s
user 10m28.892s
sys 4m57.816s
$ time spack env deactivate
real 2m30.974s
user 1m38.090s
sys 0m49.781s
```
### After
```console
$ time spack env activate .
real 0m8.937s
user 0m7.323s
sys 0m1.074s
$ time spack env view regenerate
==> Updating view at /Users/Adam/.spack/.spack-env/view

sys 0m30.717s
$ time spack env deactivate
