Rollup merge of #136472 - jieyouxu:pass-stage, r=Mark-Simulacrum
[`compiletest`-related cleanups 2/7] Feed stage number to compiletest directly

Reference for overall changes: https://github.com/rust-lang/rust/pull/136437
Part **2** of **7** of the *`compiletest`-related cleanups* PR series.

### Summary

- Pass stage number via new `--stage` compiletest flag directly from bootstrap, instead of deriving that info in compiletest by doing gymnastics on `--stage-id`.
- Just a cleanup, should have no functional changes.
