Rollup merge of #132565 - bjorn3:less_target_name_dependence, r=workingjubilee

Reduce dependence on the target name

The target name can be anything with custom target specs. Matching on fields inside the target spec is much more robust than matching on the target name.

Also remove the unused is_builtin target spec field.
