Restore commonMain to AOSP state (exceptions)

Partially fixes https://youtrack.jetbrains.com/issue/CMP-5740/Upstreaming.-compilation.-other-fixes

Restore expect exceptions to the last merged Jetpack Compose (1.8.0-alpha07) and Material3 (1.4.0-alpha04) and implement them the same way.

We can no longer use `PlatformOptimizedCancellationException` as it is a different base class, which is prohibited for actual's

## Testing
- CI passes
