Rollup merge of rust-lang#132772 - onur-ozkan:download-rustc-default, r=jieyouxu

use `download-rustc="if-unchanged"` as a global default

If `download-rustc` isn't explicitly set and the source is Git-managed, it should be totally okay to utilize "if-unchanged" behaviour. The "dist" profile already sets `download-rustc` to `false`, so this shouldn’t impact anything on CI.

This also resolves an unhandled case where `bootstrap` unexpectedly panics if `"if-unchanged"` was used with a non-Git source. Now we exits gracefully with an error message pointing the problem.
