Advantages: - Allows lexing/parsing in parallel, since they are modifying fully separate ValueStores. - Allows SemIR to reliably be stored hermetically. Disadvantages: - Creates overlapping storage of duplicate strings when multiple files are compiled together. - Prevents Ids from being uniquely compared cross-file. Per discussion, the decision is that the advantages are more important. The looser ownership remains because both SemIR checking and metaprogramming may still generate things we would want to deduplicate. It would be somewhat odd if TokenizedBuffer owned something that checking modified.
