Summary: This adds a compiler option to not drop existing manual memoization and leaving useMemo/useCallback in the generated source. Why do we need this, given that we also have options to validate or ensure that existing memoization is preserved? It's because later diffs on this stack are designed to alter the behavior of the memoization that the compiler emits, in order to detect rules of react violations and debug issues. We don't want to change the behavior of user-level memoization, however, since doing so would be altering the semantics of the user's program in an unacceptable way.
