RFR: 8224228: No way to locally suppress lint warnings in parser/tokenizer or preview features [v9]

[Archie Cobbs]

> This PR updates the `DeferredLintHandler` so that deferred warnings can be registered during parsing, before any `JCTree` nodes have been created, and it uses this new capability to update the `"preview"` and `"text-blocks"` Lint warnings so that they can be suppressed via `@SuppressWarnings` annotations. More details are provided in additional comments.

> Note: This PR depends on (i.e., includes and extends) these other "cleanup" PR's:
> * #23167
> * #23281
> * #23400
