[asan] Mark a bunch of tests as unsupported on iOS

[kubamracek]

Summary

This patch marks a few ASan tests as unsupported on iOS. These are mostly tests that use files or paths that are invalid/inaccessible on iOS or the simulator. We currently don't have a good way of propagating/copying secondary files that individual tests need. The same problem exists on Android, so I'm just marking the tests as UNSUPPORTED now.
