Rollup merge of #119548 - onur-ozkan:remove-nested-target-iteration, r=Mark-Simulacrum
Use the current target instead of iterating over all targets

Since we already iterate through targets in StepDescription::maybe_run, there is no need to iterate targets again in the install step for std.

Compared the results before and after applying the changes to install step of std, and there were no differences.
