Remove TailCall.TailPosition.NotTail metadata. (#11303)

`TailCall.TailPosition.NotTail` metadata is attached to every `IR` element that is not in tail position. Which is true for most IR elements. This is inefficient and unnecessary. This PR removes this metadata and keeps only `TailCall.TailPosition.Tail`. This removes few bytes from `MetadataStorage` from most of IR elements

# Important Notes
To check whether `ir` element is not in tail position, we used to check it with something like this `ir.getMetadata(TailCall) == Some(TailCall.TailPosition.NotTail)`, now, we simply can do it with `ir.getMetadata(TailCall) == None`
