Auto merge of rust-lang#115644 - danakj:catalyst-asan, r=cjgillot,thomcc

Enable ASAN/LSAN/TSAN for *-apple-ios-macabi

The -macabi targets are iOS running on MacOS, and they use the runtime libraries for MacOS, thus they have the same sanitizers available as the *-apple-darwin targets.

This is based on the work of rust-lang@aacf321.

Closes rust-lang#113935.
