chore: distinct operations for provisioner's 'parse', 'init', 'plan', 'apply', 'graph' (#21064)

Provisioner steps broken into smaller granular actions.
Changes:
- `ExtractArchive` moved to `init` request (was in `configure`)
- Writing `tfstate` moved to `plan` (was in `configure`)
- Moved most plan/apply outputs to `GraphComplete`
