[Plasma] If corruption is detected, hard fail next DB open

Currently if plasma.New() encounters a fatal error like ErrCorruptLSSBlock, it fails the open and returns to indexer, which restarts the indexer process.

Instead, if a recoverable fatal error (like ErrCorruptLSSBlock) is detected in NewLSStore(), auto rollback to the previous recovery checkpoint.

Updating this with discussions, in plasma since there is a continuous incrementally compacted log, rolling back to a prior checkpoint may not ensure that the corrupted page will not be accessed again since some keys in that page may go all the way back to the oldest snapshot.

So for plasma, a corruption can be handled as follows:

1. Attempt to record the fact that a corruption was detected in a non-open code path.
2. Fail NewLSStore() with the corruption error
