[MERGE #5389 @atulkatti] MSFT:17672777 Fix two pass concurrent sweep states.

Merge pull request #5389 from atulkatti:Bug17672777.AbortConcurrent.1.10.1

It is possible that AbortConcurrent gets called while we are in the concurrent sweep pass1 wait state. We handle this case correctly, just need to indicate that these can also be finished states for concurrent GC.
