System.Xaml.SafeSecurityHelper.CleanupCollectedAssemblies OOM will break the application process

### Description

The System.Xaml.SafeSecurityHelper.CleanupCollectedAssemblies method will collect the assembly in GCNotificationToken. However, memory needs to be allocated during the cleanup task which may throw System.OutOfMemoryException. As we know from the features of dotnet, any uncaught exception thrown in the background thread will cause the process to crash.

### Reproduction Steps

When the memory is insufficient, raise System.Xaml.SafeSecurityHelper.CleanupCollectedAssemblies method.

### Expected behavior

The cleanup task fail when the memory is insufficient, but not cause the application process to crash.

### Actual behavior

The application process crash with the stacktrace:

```
System.OutOfMemoryException
at System.Xaml.SafeSecurityHelper.CleanupCollectedAssemblies(Object state)
at System.Threading.QueueUserWorkItemCallbackDefaultContext.Execute()
at System.Threading.ThreadPoolWorkQueue.Dispatch()
at System.Threading.PortableThreadPool.WorkerThread.WorkerThreadStart()
at System.Threading.Thread.StartCallback();
```
