Unrolled build for rust-lang#127913

Rollup merge of rust-lang#127913 - onur-ozkan:broken-defaults, r=Kobzol

remove `debug-logging` default from tools profile

`debug-logging` conflicts with `download-rustc` option, and doesn't really make sense to enable it for a profile that is used for tool development.
