Auto merge of #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 aacf321. Closes #113935.
