Note this isn't implementing checking through imports. The parse node there is harder to access through the context, so would require examining the entity in order to get the import declaration, to get at the ImportIR. We also don't have a parse tree attached in that case, and would need to add one to SemIR::File. But I believe we do want to add that, so it's explicitly a TODO. Note GetTokenText re-lexes literal values, so there's a bit of potential overhead there. Not sure if we want a more efficient manner for comparing in cases like this.
