Summary Need to SUPPRESS_ASAN on MetadataTable::isDestroyed().

MetadataTable::isDestroyed() is used to check if the unlinkedMetadata Ref is null as a null check mitigation. Under normal circumstances, when a Ref is leaked and nullified, its memory gets poison on ASAN to ensure that it is not accessed thereafter. This conflicts with out mitigation which wishes to access it after it is nullified. The fix here is simply to apply SUPPRESS_ASAN to MetadataTable::isDestroyed(). rdar://128875400
